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. What is the area watered by the sprinkler? Use the value π = 3.14, and round your answer to one decimal place.

Answer 1

3.14*5^2=78.5
78.5*85/360=18.5

Answer 2

Explanation:

Alright, lets get started.

The given angle is 85°.

Lets convert this angle into radian first.

For this we have to multiply this with
`(\pi )/(180)`

So the angle in radian is =
`85*(\pi)/(180)=1.4835`

The formula of area is =
`(1)/(2)angle*r^2`

Area =
`(1)/(2)*1.4835*5^2`

Area = 18.5 square meter : Answer
