Circle A has a diameter of approximately 20 inches and an area of approximately 300 in2. Circle B has a diameter of approximately 60 inches. Which of these could be the area of Circle B?

4. About 2,700 in2

Step-by-step explanation:

The area of a circle (), measured in square inches, is directly proportional to the square of its diameter (), measured in inches. That is:

Where is the constant of proportionality, dimensionless.

In consequence, the following relationship between circles A and B is obtained:

The area of the circle B is now cleared:

Given that , and , then:

Therefore, the correct answer is 4.
