3. A sprinkler sprays water at a distance of 15 ft. with an angle of 145°.
How much grass is covered by water?
O:38.0 square feet
O 117.8 square feet
284.7 square feet
314.6 square feet

Respuesta :

To calculate the area covered by the water from the sprinkler, we can use the formula for the area of a sector of a circle. The formula is (θ/360) * π * r^2, where θ is the angle in degrees and r is the radius.

In this case, the angle is 145° and the radius is 15 ft. So the answer is 314.6 square feet
