Question

What is the volume of a ball if its diameter is 6 inches? Leave your answer in terms of π.

A) V = 12 π cubic inches

B) V = 36 π cubic inches

C) V = 288 π cubic inches

D) V = 27.75 π cubic inches

Answer 1

The volume of a ball if it’s diameter is 6 inches. It’s is 36 the answer is B

Answer 2

B

Explanation:

I am assuming that this ball is a perfect sphere.

The volume of a sphere is
`(4)/(3) *\pi *r^3`

We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.

`(4)/(3) *\pi *3^3`

3 cubed is 27, so now we have
`(4)/(3) *\pi *27`

27*4/3*pi=36pi
