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 smallest number of bags the groundskeeper must buy to cover the circular field?

You will need 4, 5O pound bags

Step-by-step explanation:

The area would be 66052 ROUNDED because Area = π

And per one 50 pound of grass seed = 20000 square feet of field.

And 20000*4 = 80000 which is enough but if it was 3 it would be 60000 so 4 is the least number of bags he needs.

you should at least use a calculater

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
