Air is pumped into a spherical balloon, so the balloon expands. the volume of a sphere of radius r is 4πr3/3. if the radius of the sphere after t seconds is 2t centimeters, at what rate is air being pumped in when t=4? (hint: the rate air is pumped in equals the rate that the volume of the sphere increases).
