Question

What is the volume of a sphere with a radius of 3 inches? 12π cubic inches 24π cubic inches 36π cubic inches 48π cubic inches

Answer 1

The answer is

36π cubic inches

Explanation:

Volume of a sphere is given by

`V = (4)/(3) \pi {r}^(3)`

where r is the radius

From the question

r = 3 inches

Substitute the value into the above formula and solve for the volume

That's

`V = (4)/(3)( {3})^(3) \pi \\ = (4)/(3) * 27\pi \\ = 4 * 9\pi`

We have the final answer as

36π cubic inches
