Question

A sprinkler sprays over a distance of 40 feet and rotates through an angle of 80. Find the area watered by the sprinkler.

Answer 1

Answer:

1,115.8937105551

Step-by-step explanation:

[ π x 40² ] =5,026.5482457437

[ 80 / 360 ] ft² =[,222] ft²

5,026.5482457437 X [,222] ft²= 1,115.8937105551 ft² 

A = [ π x 40² ] [ 80 / 360 ] ft² 

A = 1,115.8937105551 ft²
