A sprinkler that sprays water in a circular area can spray up to a radius of 22 ft.

Setler [38]

The sprinkler is capable of watering a circle with the radius of 22 ft. In order to find the area of this region, we must square the radius and multiply the product by 3.14, or pi (not pie :D).

Area = $\pi r^{2}$
= 3.14 x $(22)^{2}$
= 3.14 x 484
= 1519.7 $ft.^{2}$
