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.
What is the size of the field in square feet, to the nearest whole?

Answer 1

66018.5 sq feet

Explanation:

Area = πr²

To find the Radius R we need Diameter which 290 fee so:

R = Diameter / 2

R = 290/2

R = 145 ft

Now put values in Area Formula

Area = 3.14 x (145)^2

A = 66018.5 sq feet
