The given formula can be used to determine the volume (V) of a cylinder.
V= Bh = area of base x height
Which of the following is the best approximation of the volume of the cylinder below?
Step-by-step explanation:
it seems the answer is c. 3514 in3
Approximate value of the volume of cylinder is equals to 3514 in³.
What is volume?"Volume is defined amount of space occupied by any 3 dimensional body. It is useful to represents the capacity of any object ."
Formula used
Area of the base = πr²
Volume of a cylinder = area of the base × height
= πr²h
Value of π = 3.14
According to the question,
Diameter of cylinder = 11 in
Radius (r) = Diameter / 2
= 11 / 2
= 5.5 in
Height (h) = 37 in
Substitute the value in the formula we get,
Volume of cylinder = 3.14 ×(5.5)² × 37
= 3514.445 in³
≈ 3514 in³
Hence, approximate value of the volume of cylinder is equals to 3514 in³.

Martin has a bag of marbles. He removed one marble at random, recorded the color and then placed it back in the bag. He repeated this process several times and recorded his results in the table. Find the experimental probability of drawing each color.
Red: 12
Blue: 10
Green: 15
Yellow: 13
What are two different ways you could find the experimental probability of the event that Martin does not draw a red marble?
Answer:
38/50 ; or 19/25
Step-by-step explanation:
One way could be that you add all the marbles together to get your total marbles; 12 + 10 + 15 + 13 = 50.
Then you add all the colours expect red; 10 + 15 + 13 = 38.
Which would give me 38/50; which simplifed would be 19/25

8/3c-2=2/3c-12
first we'll do the LCM of both sides denominator 3 and 3=3
and multiply this with both side
3×8/3c - 2×3= 3×2/3c - 3×12

You first need to know what number 6 4/5 is, which is 6.8. To figure it out, you multiply 6 by 5 then add 4 and put the number you get on top of the fraction so it would be 34/5 = 6.8
6.9 is the answer
6.9 is bigger than 6.8 and smaller than 7

How much interest will you earn on a $90 investment at an interest rate of 3.6% over 5 months?
Answer:
well ik Yearly it would be 93$ and monthly it would be 93$
Step-by-step explanation:
It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that investment funds and/or investment companies may charge.
Please help me with this..!
Answer:
opposite sides are congruent for first under given
AD=AD for reflective property of congruency

Chloe works for an estate agent. Her monthly pay is made up of a salary of £1,600 and a bonus of £300 if she sells at least 2 properties. She is also paid 6% of the agency's annual profit at the end of the year. Last year the agency had an income of £436,000 and costs of £380,000. There were 4 months in which Chloe sold 2 or more properties. What was Chloe's total pay last year?
Answer:
22,860
Step-by-step explanation:
she makes 1600 per month x 12 months = 19,200
she sold more than 2 properties during the year so add 300
company profit = 436,000 - 380,000
= 56,000
6% of 56,000 = 3,360
add: 19,200 + 300 + 3360

Find the length of arc AB
Answer:
OH HELL NO!
Step-by-step explanation:
Answer:
[tex] m\widehat {AB} = 144\degree [/tex]
[tex]m\widehat {ACB} = 216\degree [/tex]
Step-by-step explanation:
Let the measures of the given arcs be 2x and 3x.
[tex] \because m\widehat {AB} \:\&\: m\widehat {ACB} [/tex] sums up to form a circle.
Therefore,
2x + 3x = 360°
5x = 360°
x = 360°/5
x = 72°
2x = 2*72 = 144°
3x = 3*72° = 216°
[tex] \therefore m\widehat {AB} = 144\degree [/tex]
[tex] \& m\widehat {ACB} = 216\degree [/tex]

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles. Which expression shows how many miles Emilie travels in all?
Given :
Emilie rides her bike x miles before she gets a flat tire.
She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.
To Find :
Which expression shows how many miles Emilie travels in all.
Solution :
We know, total distance covered is given by sum of all the distance she travelled.
Distance covered, D = x + 1/3 + 2 1/2
D = x + 1/3 + 5/2
D = (6x + 2 + 15)/6
D = (6x + 17)/6
Therefore, total distance travelled by Emilie is (6x + 17)/6 .
Mary is twice as old as her brother Zane.Zane is four years less than twice as old as his cousin chase.If chase is 4 years old,how old is Mary?
Answer:
Mary is 8 and that Zane and Chase are both 4 years old.
Step-by-step explanation:
For this equation, we will say Mary = M, Zane = Z, and Chase = C.
We will now convert the word problem into equations.
[tex]2m = z, 2c - 4 = z, c = 4[/tex]
Now I will solve the equations by putting C into the equation.
[tex]2(4) = 8, 2(4) - 4 = 4, c = 4[/tex]
So we can see that Mary is 8 and that Zane and Chase are both 4 years old.
