b)

Step-by-step explanation:
We are given the following information in the question:
Volume of sphere =

a) We have to find the rate at which the volume change with respect to the radius when r = 2 ft.
Differentiating, we get,

Putting r = 2

b) Approximate change in volume when radius changes from 2 to 2.2 feet


Putting the values, we get:
