Answer Posted / ganesh
take 4 textboxes , cx=centre x, cy=centre y, r=radius,
x=x co-oridnate, y=y co-ordinate.
double d;
calculate the distnace between centre and point taken
if distance less than radius(inside) else outside
simple
d = Math.Sqrt(Math.Pow((int.Parse(cx.Text) - int.Parse(x.Text)), 2) + Math.Pow((int.Parse(cy.Text) - int.Parse(y.Text)), 2));
if (d <Double.Parse( r.Text))
Label1.Text = "inside";
else
Label1.Text = "outside";
