Question

a water sprinkler sends water out in in a circle .how large is the watered area if the the watering Patten is 23 ft

Answer 1

I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.

This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.


`\sf A=\pi r^2`

Plug in what we know:


`\sf A=\pi (23^2)`


`\sf A=529\pi ft^2`

This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:


`\sf A\approx 529(3.14)`


`\boxed{\sf A\approx 1661.06~ft^2}`
