I have a circle with unknown radius.
Origo is at x=-310, y=unknown.
One known point is x=-310, y=-50, that's the top value of y.
The other known point is at x=-30.37, y=-120.11
I want to know the radius of the circle. It could be somewhere between 400
and 700 units. Anybody?
TIA,
/Tore

| Math can be broken down as follows. origin is x0, y0. radius is r. we know x0=-310. y0, r are unknowns. general equation for a circle: (x-x0)^2 + (y-y0)^2 = r^2 from point one, we know (-50-y0)^2 = r^2. from point two, we know (-30.37- -310)^2 + (...) (22 years ago, 4-Nov-02, to lugnet.cad)
