Question

If the sphere has a radius of 18 units, then what is the approximate volume of the sphere? Use 3.14 for the value of π and round your answer to the nearest hundredth.

A) 508.68 cubic units

B) 12,208.32 cubic units

C) 24,416.64 cubic units

D) 30,520.8 cubic units

Answer 1

The formula for volume of a sphere is V=4/3πr^3.
If we substitute 18 in for "r", we can work the problem out from there.

V = 4/3(3.14)(18)^3
V = 24,416.64 cubic units, so your answer will be C.

Hope that helps!
