Question

The diameter, D, of a sphere is 15 . Calculate the sphere's volume, V . Use the value 3.14 for pi , and round your answer to the nearest tenth.

Answer 1

Explanation:

The formula for the volume of a sphere is V = (4/3)πr³, were r is the radius.

If we are told only that the diameter is 15, we must find the radius before applying the above formula. The radius is r = 15/2.

The formula for the volume of a sphere is V = (4/3)πr³ yields

V = (4/3)(3.14)(15/2)^3, or

= 1,766.3 cubic units

Answer 2

V= 1767.2

Explanation:

V=4/3πr3

(I'm pretty sure I rounded that right. If not it's 1767.15 before rounding. )
