Answer 2

Answer:

Volume of the cylinder = 36 pi units³.

Step-by-step explanation:

Given : A cylinder of radius 3 units and height 4 units.

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

Solution : We have given

Radius = 3 units .

Height 4 units.

Volume of the cylinder = pi (radius)² * height.

Plugging the values of radius = 3 units , height=  4 units .

Volume of the cylinder = pi (3)² * 4.

Volume of the cylinder = pi (9) * 4.

Volume of the cylinder = 36 pi units³.

Therefore, Volume of the cylinder = 36 pi units³.
