Question

What is the general form of the equation of a circle with center at(a,b) and radius of length m?

Answer 1

Answer:

  x^2 +y^2 -2ax -2by +a^2 +b^2 -m^2 = 0

Step-by-step explanation:

The standard form equation is ...

  (x -a)^2 +(y -b)^2 = m^2

Subtracting the right side and simplifying gives the general form.

  x^2 +y^2 -2ax -2by +a^2 +b^2 -m^2 = 0

Answer 2

Answer: x2 + y2 − 2ax − 2by + (a2 + b2 − m2) = 0
