Question

A cone and a cylinder have the same height and their bases are congruent circles

If the volume of the cylinder is 90 cm^3,
what is the volume of the cone?

Answer 1

30 cm ^ 3

Explanation:

So the volume of a cylinder is πr^2 * h

The volume of a cone is πr^2 * h / 3

I feel like all you have to do is divide the volume of the cylinder by 3

90 / 3 = 30

Answer 2

30 cm³

Explanation:

As the cylinder and cone have same radius and height , volume of cone is ⅓ of volume of cylinder . You may check its always true.

So volume of cone = ⅓ × 90 = 30 cm³
