Question

Mr rivas rotating sprinkler waters his lawn up to a radius of 7ft.What is the maximum number of square feet of lawn mr rives can expect two sprinklers to cover?

Answer 1

Mr Rivas can expect 2 rotating Sprinklers can cover 307.72 square feet of lawn.

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 =
`\pi r^2 = \pi * 7^2= 153.86 \ ft^2`

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.
