Question

A water sprinkler has a range of 5meters. The jet of water from the sprinkler sweeps out at an angle of 85degrees as the nozzle turns. What is the area watered by the sprinkler?

Answer 1

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.

Answer 2

It's (85/360) of a full circle with a radius of 5meters.
