Question

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

Answer 1

V = (4/3)πr³
V = (4/3)π(4.5)³
V = (4/3)π(91.125)

Using 3.1415 again:

V = 381.69

So about 382 in³

Answer 2

the radius in 4.7...

Answer 3

then where the 4.5 is place 4.7 instead

Answer 4

V = (4/3)πr³
V = (4/3)π(4.7)³
V = (4/3)π(103.823)

Answer 5

i for some reason got 434.8
