\[Area = \pi r^2\] Typically, people use the value of pi as 3.14 and we now the area is 113.04in^2. \[113.04inches^2 = 3.14r^2\]

Now you need to divide both sides by 3.14 to isolate r and to find the radius. \[\frac{ 113.04inches^2 }{ 3.14 } = \frac{ 3.14r^2 }{ 3.14 } => 36 = r^2\]

Since r is squared, that means that we need to find the square root of 36.
