Question: F(r) = 1.5r4, where F represents the flow in cubic centimeters per second through a pipe of radius r. If r = 1, how much

F(r) = 1.5r4, where F represents the flow in cubic centimeters per second through a pipe of radius r. If r = 1, how much will a small increase in radius change the flow (try it with Δr = 0.1)? If r = 2, how will a small increase in radius change the flow?
