Question

A regulation basketball has a diameter of 9.4 inches. What is the volume of the ball?


A)
19.69 in3


B)
92.53 in3


C)
434.89 in3


D)
3479.14 in3

Answer 1

- so than 4,7 inches is the radius

V=4/3 (pir^3) =4/3 *(103,823) =138,43*pi=470,662 in^3

- so than C. will be right from your answer

Answer 2

Let's find radius r cm first
r = 9.4/2 = 4.7
V = 4/3 π r^3
V = 4/3 π (4.7^3) = 434.89 in3 ==> C
