What is the volume of the cylinder below?

A.36 pie units^3(cube)
B.90 pie units^3(cube)
C.45 pie units ^3(cube)
D.72 pie units ^3(cube)

Answer 1

It would be A


`\pi \: r {}^(2) h \\ \pi \: 3 {}^(2) * 4 \\ \pi9 \: * \: 4 \\ 36\pi`

Answer 2

Volume of the cylinder = 36 pi units³.

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.
