Question

PLEASE HELP!! Find the volume of the sphere rounded to the nearest hundredth

Answer 1

Answer:

Step-by-step explanation:

The volume for a sphere is

$V=\frac{4}{3}\pi r^3$. Our radius is 21 inches, so

$V=\frac{4}{3}\pi (21)^3$ and

$V=\frac{4}{3}\pi (9261)$. Multiplying straight across the top, using the fact that 3.14 is pi:

$V=\frac{116318.16}{3}$ and divide to get that

V = 38772.72 in^3
