The volume, V of a sphere of radius r is given by V = (4πr^3)/3. Solving for r in terms of V gives

r= f(V)= (3r/4π)1/3

Calculate the average rate of change of r with respect to V over the intervals 0.5 ≤ V ≤ 1 and 1 ≤ V ≤ 1.5.

Looking for help.

Kindly explain each step so that i could understand.
