Chantal's grandfather bought Chantal a new basketball as a present. When the ball is fully inflated, it's circumference is 30 inches. What is the volume of the ball when it is fully inflated? Use 3.14 for pi and round to the nearest cubic inch.
--------
Circumference = pi*diameter
30 = pi*d
d = 30/pi
radius = 15/pi = 15/3.14
----------------------
Volume = (4/3)pi*r^3
-------
Your Problem:
Volume = (4/3)3.14^3
----
Vol = 456 cu in when rounded down to the nearest cubic inch.
