Answer:
15 feet
Step-by-step explanation:
The area of a circle is pi*r^2, and we're using 3.14 as pi, so we get: area= 3.14 r^2
<em>We plug 706.50 into the equation and get:</em>
706.50 = 3.14 r^2
<em>Divide both sides by 3.14:</em>
225 = r^2
<em>Square root both sides:</em>
15 = r
15 feet of water spread
Area of the circular pattern is 706.50 sq. feet
Area = A = π r^2 = (3.14)* r^2
706.50 = (3.14)* r^2
r^2 = 706.50 / 3.14
r = root (225)
r = 15 feet

Pythagorean Theorem
a^2+b^2=c^2
C is the hyptonuse A and B are legs.
a^2+3^2=5^2
a^2+9=25
a^2=16
a= sqrt16
a=4
Hope this helps!
