I'm not going to write the program for you, but the way to determine whether a point lies within a circle is very easy: just compare the distance between the point and the centerpoint of the circle with its radius. If the distance is smaller, it's inside the circle, if it's greater, then the point is outside.You can calculate the distance between the point and the centerpoint using Pythagoras's method. If the point is at (PX, PY) and the centerpoint is at (CX, CY), the distance can be calculated as such:DX = (CX - PX); // X distanceDY = (CY - PY); // Y distancedistance = sqrt( (DX * DX) + (DY * DY) );
There are infinitely many points. One of these is (-7, 1)

It is not true because the distance from (0, 0) to (2, 1) works out as the square root of 5 which is the circle's radius.
Draw a circle with centre O. draw a tangent PR touching circle at P. Draw QP perpendicular to RP at point P, Qp lies in the circle. Now, angle OPR = 90 degree (radius perpendicular to tangent) also angle QPR = 90 degree (given) Therefore angle OPR = angle QPR. This is possible only when O lies on QP. Hence, it is prooved that the perpendicular at the point of contact to the tangent to a circle passes through the centre. Answer By- Rajendra Meena, Jaipur, India. email: rajendra.meena21@gmail.com
