solve my interval problem
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.

The average rate of change of a function $f(x)$ over the interval $[a,b]$ is given by $\frac{f(b)-f(a)}{b-a}.$ Does that help?
