Question

There is a water reservoir beneath a circular garden to supply a fountain in the garden. The reservoir has a 26-inch diameter. The garden has a 12-foot diameter. How much of the garden doesn't contain the water reservoir?

I have no idea how to do this please explain!!!

Answer 1

Find the areas of both circles. I suggest you use 72 inches instead for the radius of the garden.

A = pi * r^2

Answer 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!!!!!

Answer 3

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

Answer 4

A - pi * radius squared

Yes -- subtract the area of the reservoir from the area of the garden.

Answer 5

The answer is417.62 after finding the area of both objects and subtracting them
