First get the formula for the area of a circle...then get the diameter..then do some math

3.1417 * r squared
r is the radius, which is the distance from the center to the outside of the circle.
r squared is the radius *itself. the r squared is figured first, so if the radius is 3, then 3*3 =9.
9*3.1417=28.2753

Take the radius, square it and multiple it by pi
The circumference is radius times pi,
or radius times 2 times pi

pi x r squared ===>>> 22/7
r = radius of the circle
pi x ( rxr )

pi multiplied by the radius squared
(Radius is the distance from the centre to the edge of the circle.)
(Pi is 3.141592654...usually just 3.14 is ok)

pi (about 3.14) x r (radius--center of the circle to the outside distance) x r (radius again)

pi r squared.
pi times the square of the radius.
Sorry I had a 2 in there and it was wrong - amended now.
