Question

. A sphere has a diameter of 18 meters. Find the volume of the sphere, in cubic meters, in
terms of π.

Answer 1

\[r=2d\]where r is the radius and d is the diameter.\[V=\frac{4\pi}{3}r^3\]where V is the volume and r is the radius.
Do not use a number for pi. Leave it as a symbol in the answer. That will make your answer in terms of pi.
