Mr. townes created a 2-foot 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 5o cover his garden path?

The bags of stones Mr. Townes will need are 20 bags.

Given:

The radius of the circular garden is 7 feet.

The width of the circular path around the park is 2 feet.

To find:

The bags of stones needed by Mr. Townes to cover the garden path.

Solution:

The radius of the circular garden = 7 ft

The width of the circular path around the park = 2 ft

The radius of the  inner circle = r = 7 ft

The radius of the outer circle = r' = 7 ft + 2 ft = 9 ft

The area of the inner circle = A

The area of the outer circle = A'

The area of the circular garden path = C

Mr. Townes needs 1 bag of stones for every 5 square feet of a path, then for 100.53 square feet he will need:

The bags of stones Mr. Townes will need are 20 bags.
