Question

The volume of a growing spherical cell is given below, where the radius is measured in micrometers (1 µm = 10^-6m).
V = 4/3pi r^3
(a) Find the average rate of change of V with respect to r when r changes from 2. Evaluate your answers numerically.
(i) 2 to 5 µm ? µm2
(ii) 2 to 3 µm ? µm2
(iii) 2 to 2.1 µm ? µm2

Answer 1

it got cut off...here's the rest:

(i) 2 to 5 µm ? µm2
(ii) 2 to 3 µm ? µm2
(iii) 2 to 2.1 µm ? µm2

Thank you

Answer 2

nevermind i got it
