The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
well you would times that by: R2=D*3.14(pie)=C
A standard form of a linear equation would be: ax + by = c
The standard form of an equation is Ax + By = C. In this type of equation, x and y are variables while A, B, and C are integers.
(x - h)2 + (y - v)2 = r2
