Question

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is452.16 square​ feet? Use 3.14 for .

Answer 1

12 feet

Explanation:

It asks how many feet away from the sprinkler can water be spread. Therefore, in this scenario, we require the radius.

Area of a circle :

Area (circle) = πr²

Solving :

⇒ 452.16 = 3.14 × r²

⇒ r² = 452.16 ÷ 3.14

⇒ r = √144

⇒ r = 12 feet

Answer 2

We need radius

Let that be r

• πr²=452.16
• 3.14r²=452.16
• r²=144
• r=√144
• r=12ft
