The volume of the given cylinders is 1. V≈1244.07 2. V≈54286.72 3. V≈23816.41 4. V≈254.47 5. V≈4247.43 6. V≈21714.69 7. V≈4712.39.
What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
A.
a) The height of the cylinder is given as 11 in and the radius is 6 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 6^2 x 11
= 1244.07cubics in
b) The height of the cylinder is given as 30 in and the radius is 24 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 24^2 x 30
= 54286.72 cubics in
c) The height of the cylinder is given as 21 in.
The radius of the base of the cylinder is given as 19 in.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 19^2 x 21
= 23816.41 cubics in
B.
d) The height of the cylinder is 9ft the radius is 3 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 3^2 x 9
= 254.47 cubics ft
e) The height of the cylinder is 8 ft the radius is 13 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 13^2 x 8
= 4247.43 cubics ft
f) The height of the cylinder is 27 ft the radius is 16 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 16^2 x 27
= 21714.69 cubics ft
g) The height of the cylinder is 15 ft the radius is 10 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 10^2 x 15
= 4712.39 cubics ft

What is the volume of a box with width 2 2/3 inches, length 3 1/3 inches, and height 2 1/3 inches ?
Answer:
The volume of a box is:
V = 560 cubic inches or [tex]20\frac{20}{27}[/tex] cubic inches.
Step-by-step explanation:
Given
The width of a box = w = 2 2/3 inches
i.e. [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex]
The length of a box = l = 3 1/3 inches
i.e. [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex]
The height of a box = h = 2 1/3 inches
i.e. [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex]
Using the formula to determine the volume of a box
[tex]V=w\times l\times h[/tex]
substitute [tex]\:w=2\frac{2}{3}=\frac{8}{3}[/tex], [tex]l=\:3\frac{1}{3}=\frac{10}{3}[/tex] and [tex]\:h=2\frac{1}{3}=\frac{7}{3}[/tex],
[tex]V=\frac{8}{3}\times \frac{10}{3}\times \frac{7}{3}[/tex]
Apply the fraction rule: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{8\times \:10\times \:7}{3\times \:3\times \:3}[/tex]
[tex]=\frac{560}{27}[/tex] or [tex]20\frac{20}{27}[/tex] cubic inches
Therefore, the volume of a box is:
V = 560 cubic inches or [tex]20\frac{20}{27}[/tex] cubic inches.

Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta’s wires than one of Tia’s?
First, Tia’s wire is 4 meters and 8 centimeters long, so that means it’s 408 centimeters long, then you divide that by 10:
tia = 408/10 = 40.8 cm
Now, Marta’s wire is 540 centimeters long and we have to divide that into 9 pieces:
Marta = 540/9 = 60 cm
Finally subtract Marta’s and Tia’s pieces: 60 - 40.8 = 19.2
So Marta’s pieces are 19.2 centimeters longer than Tia’s
Answer:
19.2

Lea earned $24 babysitting. She spent ⅔ of that amount on a gift for her bestie, ¼ on snacks. What fraction of her earning is left? How much money does she have left?
Answer:
5/12, $10
Step-by-step explanation:
Lea earned $24 babysitting. She spent ⅔ of that amount on a gift for her bestie, ¼ on snacks. What fraction of her earning is left? How much money does she have left?
Let the total amount earned be 1
Given
Amount on snacks = ¼
Amount on babysitting = ⅔
Required
Fraction left
Fraction left = Total -(snacks+babysitting)
Fraction left = 1-(1/4+2/3)
Fraction left = 1-(3+4/12)
Fraction left = 1-7/12
Fraction left = 5/12
Amount of money she has left = 5/12 × 24 = 5×2 = $10
Hence she has $10 left

2) Angelina is deciding which bank would give her the
best simple interest rate on a $300 deposit. One bank
says that she will have $320 in her account if she leaves
the principal for two years. Is this enough information
for Angelina to find the interest rate? Explain.
HELPPPP
Answer:
3.33%
Step-by-step explanation:
Given that :
Final amount A= 320
Principal P = 300
Time (t) = 2 years
Yes, the information is enough to obtain the interest rate :
Using the relation :
A = P(1 + rt)
r = interest rate
320 = 300(1 + r*2)
320 = 300(1 + 2r)
320/300 = 1 + 2r
1.0666666 = 1 + 2r
1.0666666 - 1 = 2r
0.0666666 = 2r
r = 0.0666666 / 2
r = 0.0333333
(0.0333333) * 100% = 3.33%
Based on the information given the interest rate is 53.33%.
Interest rate:Amount= Principal× Interest rate ×Time/100
Let r represent the interest rate
Hence:
320 = 300×r×2 years/100
320×100/300×2=r
r=320/3×2
r=160/3
r=53.33 or 53 1/3
Inconclusion the interest rate is 53.33%.

Help pls show work also did she sell more or less 40lb of seed
Answer:
37 1/8 lbs of bird seed
Step-by-step explanation:
I solved this quickly on my calculator, but I will show my work here :)
First I would do what I think is easiest. I will add the whole numbers separately and add the fractions separately. This is what I mean:
8+12+16 = 36
1/4 + 3/8 + 1/2 = 1 1/8
After I've done that then I'll add both of these answers:
36 + 1 1/8 = 37 1/8
Here's how I added the fractions:
To add fractions you must make sure the denominators ( the number below the line) are all the same. We do this by multiplying a number that will get all denominators the same, we also have to multiply the numerator (number above the line) by the same number to even out the fraction. After that you only add the numerators, but keep the denominators the same. Here's how:
(2/2) 1/4 × 3/8 --> 2/8 + 3/8 = 5/8
Then we add the 5/8 to the 1/2
(4/4) 1/2 + 5/8 --> 4/8 + 5/8 = 9/8
If you haven't noticed, 9/8 is an improper fraction because the numerator is larger than the denominator. We can fix that by turning it into a mixed fraction (a fraction with a quotient and remainder. Ex. 2 1/3)
I'm sure it would still be acceptable to write your answer as 36 9/8 lbs, but in case your teacher won't accept that, I provided a photo of how to fix it :). You will need to do long divison.
So 9/8 turns into 1 1/8.
Add everything:
36 + 1 1/8 = 37 1/8

What is the slope of D and E??
Answer:
-4 and 0
Step-by-step explanation:
Rise over Run would give us the slope.
In the first graph, It goes down 4 while it goes 1 to the right.
This means that -4/1 = -4.
The second graph does not go up or down, meaning 0, while it goes 1 to the right.
This means that 0/1 = 0.
Two less than three times a number is the same as six more than twice the number. Write an equation and solve to find the number.
Answer: 8
Step-by-step explanation:
Let the number be represented by x.
Two less than three times a number is the same as six more than twice the number. This will be:
(3 × x) - 2 = (2 × x) + 6
3x - 2 = 2x + 6
Collect like terms.
3x - 2x = 6 + 2
x = 8.
The number is 8
