Question

The radius of a sphere is 6 units.




Which expression represents the volume of the sphere, in cubic units?

Three-fourthsπ(6)2
Four-thirdsπ(6)3
Three-fourthsπ(12)2
Four-thirdsπ(12)3

Answer 1

Volume of a sphere: V = (4/3)πr^3. With r = 6, V = (4/3)π(6)^3 = (4/3)π(216) = 288π cubic units.

So the correct expression is: Four-thirdsπ(6)3.
