Question

The diameter D of a sphere is 19.4 CM calculate the spheres volume

Answer 1

3821.05

Explanation:

To find the volume of a sphere, use the formula
`4/3\pi r^3`.

Replace R with 9.7 because the diameter is 19.4 and the radius would be half of that, and the question said to use 3.14 as pi.

So it would be:
`4/3*3.14*9.7^3`

Which would equal: 3821.05

Answer 2

The spheres volume would be 16.5
