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,

Gavin
