Question

What is the volume of the cylinder below?

Answer 1

Answer:

B) Volume of cylinder is  $36 \pi$ units³.

Step-by-step explanation:

Given : Cylinder.

To find : what is the volume of the cylinder below.

Solution : We have given cylinder with radius = 3 units.

Height = 4 units .

Volume of cylinder = $\pi * radius^{2} * height.$

Plug the values

Volume of cylinder = $\pi * (3)^{2} * 4$.

Volume of cylinder = $\pi* 9 * 4$.

Volume of cylinder = $\pi 36$ units³.

Volume of cylinder is  $36 \pi$ units³.

Therefore, B) Volume of cylinder is  $36 \pi$ units³.

Answer 2

Answer:

B

Step-by-step explanation:

The formula for volume of cylinder is given below:

volume of cylinder = $\pi r^2 h$

Where r is the radius (here, it is given as 3)

h is the height, the perpendicular distance from base to top (here, it is 4 NOT 5 since 5 is the 'slant height')

Plugging in the available info , we get our answer:

$\pi r^2 h\\=\pi (3)^2 (4)\\=36\pi$

B is the correct answer
