Question

What is the volume of a sphere with a diameter of 12 inches? Use 3.14 for pi. Round your answer to the nearest hundredth.

904.32 in3

1599.65 in3

3500.12 in3

7238.20 in3

Answer 1

use the formula for a sphere's volume and solve for r

Answer 2

the formula is V= 4/3 *pi * r^3

so first work out r^3

then multiply by 4

then divide by 3

then multiply by pi (3.14)

then round ot the nearest 100th

Answer 3

Stilll dont understand can you help?

Answer 4

I cannot be any clearer

the formula for volume of a sphere is 4/3 * pi *r^3

so follow the steps I wrote above - each step is a simple multiplication (or division)

I am not going to write the answer so try a little work for yourself

Answer 5

r is the radius - you are told the diameter is 12" - so what is the radius?
