Question

A tennis ball has a radius of 6.7 centimeters. What is the volume of a tennis ball? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answer 1

A tennis ball is a sphere
Volume of a sphere ===> $v= \frac{4}{3} \pi r^3$
Plug in the given info 
$v= \frac{4}{3} (3.14) (6.7)^3$

Do the math to get a final answer of: 
$v= \frac{4}{3} (3.14) (6.7)^3=1259.19cm^3$

Answer 2

Answer: Volume of tennis ball= 1,259.20 cubic centimeters.

Explanation:-

Radius of tennis ball = 6.7 centimeters

We know that volume of sphere$=\frac{4}{3}\pi\ r^3$

Volume of tennis ball$=\frac{4}{3}\cdot3.14\cdot(6.7)^3$

$=\frac{4}{3}\cdot944.39=1,259.1944\approx1,259.20\ cm^3$

Therefore, volume of tennis ball= 1,259.20 cubic centimeters.
