What is the area of the base of the cone below?

Given:

Given that the height of the cone is 12 ft.

The volume of the cone is 90 ft³

We need to determine the area of the base of the cone.

Area of the base of the cone:

The area of the base of the cone can be determined using the formula,

where the base area is

Substituting the value of A in the above formula, we get,

Substituting V = 90 and h = 12, we get;

Dividing both sides by 4, we get;

Thus, the area of the base of the cone is 22.5 square feet.

Hence, Option c is the correct answer.
