Answer to Question #1694 in Calculus for Abhilash

Question

The volume V of a growing spherical cell is given below, where the radius is measured in micrometers (1 µm = 10-6m). Evaluate your answers numerically. (Round the answers to one decimal place.)

V = 4/3pi r^3

(b) Find the instantaneous rate of change of V with respect to r when r = 5 µm. Evaluate your answer numerically.
V'(5) = 4 µm3 / µm
