Question

The radius of a basketball is 4.7 inches.what the volume of the basketball? Round to the nearest 10

Answer 1

The volume of a sphere is 4/3(pi)r^3
Substituting,

4/3(pi)(4.7^3) = 303.7 cubic inches.

Answer 2

The formula for the volume of a sphere is $V= \frac{4}{3} \pi r^3$. Plugging in 4.7 for your radius, we get $V= \frac{4}{3} \pi 4.7^2= \frac{4}{3} \pi 22.09= \frac{88.36}{3} \pi$, which is roughly 29.453π≈92.530.
