Question

Find the volume of the cylinder. Express your answer in terms of π.

A: 26π in3


B: 800π in3


C: 640π in3


D: 160π in3

Answer 1

Given:

The radius of the cylinder is 8 inches.

The height of the cylinder is 10 inches.

We need to determine the volume of the cylinder.

Volume of the cylinder:

The volume of the cylinder can be determined using the formula,

`V=\pi r^2 h`

where r is the radius and h is the height.

Substituting
`r=8` and
`h=10` in the above formula, we get;

`V= \pi (8)^2 (10)`

Simplifying, we get;

`V=\pi (64)(10)`

Multiplying, we get;

`V=640 \pi`

Thus, the volume of the cylinder is 640π in³

Hence, Option C is the correct answer.
