Question

A water sprinkler has a range of 5 meters as shown. The jet of water from the sprinkler sweeps out at an angle of 85° as the nozzle turns. Solve for the total area watered by the sprinkler. Use the value π = 3.14, and round your answer to one decimal place.
a. 15.6 Square Meters
b. 17.8 Square Meters
c. 18.5 Square Meters

Answer 2

I found the image that accompanied this problem.
We need to solve for the area of the sector.

A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347 

Answer is C. 18.5 square meters.
