A water sprinkler sends out water in a circular pattern. How many feet away from the sprinkler can it spread water is the area formed by the watering pattern is 530.66 square feet? Use 3.14

r= 13ft

Step-by-step explanation:

You are looking for the radius

The Area of a circle is  

πr2=530.66

(3.14)r2=530.66

Divide both sides by 3.14

r2=169

Square root both sides to get radius

r=13 feet

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

the correct is answer is a 9-sided polygon!
