Answer:
c.
Step-by-step explanation:
We have been given that the area in square units of an expanding circle is increasing twice as fast as its radius in linear units
We will use derivatives to solve our given problem.
We know that area (A) of a circle is equal to .
Let us find derivative of area function with respect to time.
Bring out constant:
Using power rule and chain rule, we will get:
Here
represents change is radius with respect to time.
We have been given that area of an expanding circle is increasing twice as fast as its radius in linear units. We can represent this information in an equation as:
Therefore, the radius is and option 'c' is the correct choice.
