Question 297287: Please leave the answers in terms of (pi)
a)Find the polynomial for the sum of the areas
of the three circles
Find the sum of the areas when r=5 and r=11.3
There are three circles. The first one is a big circle with (r) in the middle.
The second circle is medium with a (3) in the middle.
The third circle is small with a (2) in the middle.

area of a circle is A=pi%2Ar%5E2
Find the sum of the areas when r=5 and r=11.3
S=%28pi%2Ar%5E2%29%2B%28pi%2Ar%5E2%29
S=%28pi%2A5%5E2%29%2B%28pi%2A11.3%5E2%29
S=%2825pi%29%2B%28127.69pi%29
S=%28152.69pi%29

big circle=A=pi%2Ar%5E2
medium circle=A=pi%2A3%5E2 or9%2Api
small circle=A=pi%2A2%5E2 or4%2Api
