Agroundskeeper needs grass seed to cover a circular field 290 feet in diameter

a store sells 50 pins bags of grass seed. one pound of grass seed covers about 400 square feet of field.
what is the smallest number of bags the groundskeeper must buy to cover the circular field?

165

Step-by-step explanation:

First we need to find the area of the field, A = r^2 * pi

The radius is 290 / 2 = 145 feet

A = 145 * 145 * 3.14 = 66018.5 sqr feet

One bag covers 400 sqr feet

Divide the Area by 400 sqr feet to find number of bags needed.

66018.5 / 400 = 165

He will need at least 165 bags to cover the field
