Question

A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter.

A store sells 50-pound bags of grass seed. one pound of grass seed covers about 400 square feet of field.

How many square feet does each 50-pound bag cover?

Answer 1

4 bags

Explanation:

A = r²

A = 3.14 * 145² = 66,018.5 ft²

66,018.5 ÷ 400 ≈ 165.05 lb.

165.05 ÷ 50 ≈ 4 bags
