Area in a circle = (pi) times (square of the circle's radius)

You can use any number you want to use for (pi) in that formula. The closer your

choice is to the real value of (pi), the closer your result will be to the real area.

If you decide to use 22/7 , then your result will be only about 0.04% bigger than the

real area. That's very good accuracy, and that's why a lot of people use 22/7 for (pi)

even though it doesn't look very impressive.
