Find the areas of both circles. I suggest you use 72 inches instead for the radius of the garden. A = pi * r^2

i am still confused so you find the areas of both circles, but whats the formula? pi times r times 2? please help me!!!!!

audrey · Answer

wait so after you find the areas you subtract the reservoir from the garden to get the answer?

A - pi * radius squared Yes -- subtract the area of the reservoir from the area of the garden.
