Asked by Ty

Don decided to do some landscaping in his backyard. He began by watering the lawn. The rotating sprinkler that he installed can spray an area with a radius of 7 feet.

What is the maximum area the sprinkler can cover?

a. 21.98 ft(2)
b. 28.26 ft(2)
c. 43.96 ft(2)
d. 153.86 ft(2)


I've been trying to figure it out but I have no clue how to solve this question, can anyone help me for that? Thanks!

So ... multiply pi by the square of the radius to get the area. Use 3.14 for pi.

(7 x 7) x 3.14 = the area of this circle that the sprinkler can cover.
