Question

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

The radius is 7cm and the length is 15 cm.

a) 602 cm pie ^3
b) 735 cm pie ^3
c) 812 cm pie ^3
d) 518 cm pie ^3

Answer 1

The correct option is b.

Explanation:

Given information: Radius of the cylinder r = 7 cm and length or height h is 15 cm.

The volume of a cylinder is

`V=\pi r^2h`

Where, r is the radius and h is height.

Substitute r=7 and h=15 in the above formula.

`V=\pi (7)^2(15)`

`V=\pi* (7)^2* (15)`

`V=\pi* 49* 15`

`V=\pi* 735`

`V=735\pi`

The volume of the cylinder is 735π cm³. Therefore the he correct option is b.
