area of circle/ geometry help

Hey Guest!

 

We use the formula:

 

\(A=\pi{r}^2\), to find the area of the circle,

 

Where A is the area, r is the radius, and π is the ratio of the circumference to the diameter, or just 3.1415...

 

Since π is a constant, all we need to do, is find the radius of the circle to get the area. 

 

Since the radius is half of the diameter, it is equal to \(11\div2=5.5\)

 

We plug our values into the formula to get:

 

\(30.25\pi\)

 

I hope this helped,
