Find the perimeter AND area of each figure. Include your work. (You only need to find the AREA of the CIRCLE IMAGE. For the RECTANGLE and TRIANGLE both area and perimeter are required, and full work must be shown for all 3.)

2461.76

Step-by-step explanation:

A=πr^2

First, find the area of the smaller circle.

A = (3.14)(21^2)

A = 1384.74

Next, find the area of the larger circle. Since it was stated that both circles have the same center, the radius would be 28.

A = (3.14)(28^2)

A = 2461.76

Now subtract the area of the smaller circle from the larger circle.

2461.76 - 1384.74 = 1077.02

Since 1077.02 is already rounded to the nearest hundredth, leave it as it is.
