What is the forulae for a circles area, is it Pie*Radius^2?[/i]
Yep (pi, not pie
).
(x - h)^2 + (y - k)^2 = r^2
Quote:(x - h)^2 + (y - k)^2 = r^2
That is not the formula for finding the area of a circle
That is the formula for finding the equation of a circle. Shows wether a point is on the circle or not, etc....
