A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).
To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.
Yes, it does.

How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
