Question

A cylinder has a height of 16 feet and a diameter of 20 feet. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answer 1

v = 5024

Explanation:

The formula used to find the volume (v) of a cylinder is
`v = \pi r^2h`, where r = radius and h = height. Here, we are using 3.14 instead of pi.

We are given a height of 16 ft, and a diameter of 20 ft. The radius is simply half of the diameter, so our radius is 10 ft. Put these two values into the formula and solve.

`v = 3.14*10^2*16`

If you were to be using pi, your answer exactly would be v = 5026.55. Using 3.14, it is v = 5024.

Answer 2

V = 5024 ft³

Explanation:

the volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

since diameter = 20, then r = 20 ÷ 2 = 10

V = 3.14 × 10² × 16

= 3.14 × 100 × 16

= 314 × 16

= 5024 ft³
