Area of a circle formula
A = π r²
Divide 112.07 by π
112.07 / 3.141592654 = 35.67298894
√35.67298894 = √r²
5.972686912 = r
5.97 feet rounded to two decimal places

Area of a circle is A=∏r^2
∏= pi
A= 112.07
so divide 112.07 by ∏ = 35.69
for r^2
r=√35.69
r=5.97

Area circle = pi *r^2 Thus r = sqrt(Area/pi) = sqrt(112.07/3.14)=sqrt(35.69)

A=(pi)(r^2)
112.07=(pi)(r^2)
r^2=35.67298894
r = 5.97

Area = pi * radius^2
112.07 = pi * r^2
35.673 = r^2
5.97 = r (approx)

A=pi r^2
112.07=pi r^2
35.673=r^2
5.97=r
about.. ish...
