Answer:
Mr Rivas can expect 2 rotating Sprinklers can cover 307.72 square feet of lawn.
Step-by-step explanation:
Given:
Radius of sprinkler = 7 ft
We need to find the area in square feet of lawn covered by 2 sprinklers.
Now we will find the area covered by 1 sprinkler
area covered by 1 sprinkler is equal to π times square of the radius.
framing in equation form we get;
area covered by 1 sprinkler = [tex]\pi r^2 = \pi \times 7^2= 153.86 \ ft^2[/tex]
Now we can say that area covered by 1 sprinkler will be equal to area covered by 2 sprinkler.
So Total Area Covered by 2 Sprinkler = 153.86 + 153.86 = 307.72 sq ft
Hence Mr Rivas can expect 2 rotating Sprinklers can cover 307.72 square feet of lawn.
