Mr Townes created a 2foot wide garden path around a circular garden. The radius of the garden is 7 feet. He wants to cover the path in stones. If mr. Townes needs 1 bag of stones for every 5 square feet of path, how many bags of stones will he need to cover his garden path?

area path= area outerarea inner
= PI (9^2  7^2)= PI*(8149) figure that out.
Now, bags of stones=1bag/5 * area
