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!
