Step-by-step explanation: <u>Rate</u> <u>of</u> <u>change</u> measures the slope of a curve at a certain instant, therefore, rate is the derivative.
A. Area of a circle is given by
So to find the rate of the area:
Using
Then
Multipying and simplifying:
The rate at which the area is increasing is given by expression .
B. At t = 5, rate is:
At 5 seconds, the area is expanded at a rate of 1.76 cm/s.
