Answer:

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

Step-by-step explanation:

use the formula V=πr^2h

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.

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

Answer: y=−2x+8

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

Let's rewrite this in slope intercept form, and isolate y on the left side. First, subtract 6x from both sides:

3y = 24 - 6x

Then divide both sides by 3:

y = -2x + 8

Now that it's in y = mx+b form, we can see that the slope is -2, and the y intercept is 8.

No time

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%.

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%.

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

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
