A tennis ball has a diameter of 12 cm. What is the volume of the tennis ball in cubic units? Assume that π = 3.14 and round to the nearest tenth when necessary.

Step-by-step explanation:

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
