Dan is fertilizing his garden. the garden is in shape of a rectangle l. its lenth is 15 feets and its width is 13 feet. suppose each bag of fertilizer covers 39 square feet. how many bags will need to cover the garden?

A = l*w

A = 15*13

A = 195 ft^2

Each bag covers 39 ft^2

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
