Challenge The radius of Circle A is 5 ft. The radius of Circle B is 4 ft greater than the radius of
Circle A. The radius of Circle C is 2 ft greater than the radius of Circle B. The radius of Circle D is 3 ft
less than the radius of Circle C. What is the area of each circle? How many times greater than the
area of Circle A is the area of Circle D?
The area of Circle A is ft2
(Simplify your answer. Type an exact answer in terms of T.)

Step-by-step explanation:

The radius of Circle A is 5 ft. If Circle B has a radius 4 ft greater than Circle A, then the radius of Circle B is 9 ft. If Circle C has a radius 2 ft greater than Circle B, then the radius of Circle C is 11 ft. If Circle D has a radius 3 ft less than Circle C, then the radius of Circle D is 8 ft.

Now that we have the radius for each circle, we can use the area formula to find the area of each circle. We will use 3.14 in the placement of .

The area of Circle A is 78.5 ft².

The area of Circle B is 254.34 ft².

The area of Circle C is 379.94 ft².

The area of Circle D is 200.96 ft².

Now that we know the area for each of the circles, we need to find how many times greater the area of Circle D is to the area of Circle A. We can do this by dividing the area of Circle D and the area of Circle A.

200.96 ÷ 78.5 = 2.56

The area of Circle D is 2.56 times greater than the area of Circle A.
