I think the final answer would be 314.16 ft squared.This is because if it sprays 20 feet out on each side, the radius would be 20. With a radius of 20, we can solve with the equation A=πr2 to give us the final area of 1256.64 ft squared. It states, however that it only covers 1/4 of the circle, so we can divide 1256.64 by 4 and get the final area of 314.16 ft squared.

Answer:

100 pi ft^2

Step-by-step explanation:

The area of the grass that would be watered would be one quarter of the area of the circular lawn of 20 ft radius.

So the area in question would be A = (1/4) * pi * (20 ft)^2 = 100 pi ft^2.
