Question

What is the volume of the cylinder below?

Answer 1

The answer is B.

Explanation:

Given that the formula of volume of cylinder is, v = π×r²×h where r represents radius and h is height of the cylinder. So you have to substitute the value of r and h into the formula :

`v = \pi * {r}^(2) * h`

Let r be 7 units,

Let h be 4 units,

`v = \pi * {7}^(2) * 4`

`v = \pi * 49 * 4`

`v = \pi * 196`

`v = 196\pi \: {units}^(3)`
