## anonymous one year ago The area of a circle is 113.04 in. 2. What is the radius of the circle? 36 inches 18 inches 12 inches 6 inches

1. calculusxy

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

2. calculusxy

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

Not really

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

$\sqrt36 = r$
