Using locus find the equation of the circle whose centre is at (-3,-2) and radius 8 units.how solve this problem?
1 Answer
We know that a circle is the locus of points equidistant from the center point. The distance between two points is defined by the following equation:
Replace
Replace specific point
Replace the distance, d, with the specified radius,
Flip the equation:
Square both sides:
This is how the general Cartesian form for the equation of a circle is derived:
where
