Question

A sphere has a diameter of 6 ft. Find the volume of the sphere.

some help please

Answer 1

The Diameter should be 2r hopefully this is right.

Answer 2

exact = 36pi , rounded = 113.097

Explanation:

The volume of a sphere is 4/3*pi*r^3

a radius is half of a diameter, so the radius is 3 ft.

4/3*pi*3^3

3 cubed equals 3*3*3 which equals 27.

so, now you get 4/3*pi*27

so you get approximately 113.097, or 36pi

Hope this helps!
