The radius of a mini basketball is 4inches. A pump can inflate the ball at a rate of 6 cubic inches per second. How long will it take to inflate the ball? Round to the nearest tenth

Assuming the problem means that the basketball has a radius of 4 inches when it is FILLED up, then here we go:

Sphere: \(\frac{4}{3}\pi{r^3}\)

Substitute and solve for volume:

\(\frac{256}{3}\pi\text{ cubic inches}\)

We divide:

\(\frac{256/6}{3}\pi\)

We evaluate:

44.6804288510548372040483

We round:

44.7 seconds
