Answer:
The smallest number of bags the groundskeeper must buy to cover the field is 165 bags.
Given:
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.
To find:
The smallest number of bags the groundskeeper must buy to cover the field.
Solution:
Diameter of the field = 290 feet, radius = 145 feet
Area of the circular field = \pi r^{2}=πr
2
= \pi \times 145 \times 145π×145×145 = 66018.5
No of bags to be brought = \frac{66018.5}{400}
400
66018.5
= 165 bags.
