Step-by-step explanation:
Answer:
Rate of increase of radius = 0.0064 ft/sec
Rate of increase of surface area = 1.61 
Step-by-step explanation:
Given that:
Rate of change of volume of a spherical balloon = 8 cubic feet per minute

Radius,
= 10 feet
To find:
The rate of change of radius at this moment and rate of change of surface area at this moment?
Solution:
First of all, let us have a look at the formula:

Now, differentiating the volume and area, we get:
