A cylinder and a cone are shown below.

-

12 in.

-

12 in.

Volume of cylinder = 2512 in.

Volume of cone = 1256 in.

Which explains whether the bases of the cylinder and the cone have the same area?

O The bases have the same area because the heights are the same.

O The bases have the same area because the volume of the cone is 5 the volume of the cylinder.

O The bases do not have the same area because the volumes are not the same.

O The bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given

the same heights.

Answer:

The bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given the same heights.

Explanation:

Recall :

V1 = volume of cylinder = πr²h

V2 = volume of a cone = 1/3πr²h

From the diagram, both have height, h of 12

Radius = r

V1 = 2512 in

V2 = 1256 in

From the ratio :

2512 = πr² * 12

1256 = 1/3πr² * 12

12 cancel out as well as r² and π

If the bases have the same area `, then 2512 should be equal to (1256 * 3)

2512 in ≠ 3868 in

A cylinder and a cone are shown below. - 12 in. - 12 in. Volume of cylinder = 2512 in-example-1
