1. ## Baloon Diameter Problem

How much longer does it take to inflate a balloon to a diameter of 25 inches instead of a diameter of 5 inches. Assume the rate that air enters is constant.
_____________________times as long

I've tried, 5, 10, 15, and 25 but none of those right. I can't figure out how to go about this problem :/

$V = \frac{4}{3}\pi r^3$

radius is $5$ times larger ... volume is $5^3$ times larger
