Question

is my answer to this question correct

A spherical balloon is losing air at the rate of 2 cubic inches per minute. How fast is the radius of the ballon shrinking when the radius is 8 inches.

Answer= .0024

Answer 1

V=4/3 PI r^3
dV/dt=4/3 PI * 3r^2 dr/dt

solve for dr/dt

dr/dt=dV/dt / 4PIr^2

Wondering why you did not round it up to .0025
