Answer:
56.52 feet.
Step-by-step explanation:
We have been given that a rotating sprinkler sprays at a steady stream of water that is nine feet long. We are asked to find the approximate circumference of a circular area it sprays with water.
We will use circumference of circle formula to solve our given problem.
[tex]\text{Circumference of circle}=2\pi r[/tex], where r represents radius of the circle.
[tex]\text{Circumference of circular area}=2\times 3.14\times \text{9 ft}[/tex]
[tex]\text{Circumference of circular area}=56.52\text{ ft}[/tex]
Therefore, the circumference of the circular area is approximately 56.52 feet.
