You first need to find the area of the ring-shaped path.

OpenStudy (mathstudent55):

Do you know how to find the area of a ring?

OpenStudy (matlee):

Oh hi and yes

OpenStudy (matlee):

is it 725

OpenStudy (mathstudent55):

To find the area of the ring, find the area of the outer circle, and subtract from it the area of the inner circle. I don't get 725 yd^2 for the area of the ring. Once you have the area of the ring, divide it by the coverage of 1 bag to find how many bags are needed. Round the number of bags up to the nearest whole number.
