Question

A rotating sprinl;er sprays at a steady stream of water that is nine feet long. If the sprinkler makes a full rotation, what is the approximiate circumference of a circular area it sprays with water?(use 3,3.14, or 22/7 for pie)

Answer 1

56.52 feet.

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.

`\text{Circumference of circle}=2\pi r`, where r represents radius of the circle.

`\text{Circumference of circular area}=2* 3.14* \text{9 ft}`

`\text{Circumference of circular area}=56.52\text{ ft}`

Therefore, the circumference of the circular area is approximately 56.52 feet.
