How do you find the equation of the circle given diameter at (4, -3) and (-2, 5)?
If the diameter is
then center is at
the radius is
The general equation of a circle
In this case we have
Formula for the eqn. of a circle having
Accordingly, the reqd. eqn. is
Extremities of a diameter are
Centre, being midpoint of diameter, we get the centre
Radius = Distance between the Centre & any end point of given diameter
Hence the eqn.
