How do you determine the area of a circle? Could you give an example please?
pickupchik [31]
To determine the area if the circle, you must know the diameter or the radius of a circle.

If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)
a = \pi {r}^{2}
If you know the diameter, just divide the diameter to get the radius then use the same equation.
