Name: Date:The graph above shows a circle centred at the origin, O. The point P lies on the circle and has coordinates (18, -24). Line QR is a tangent to the circle passing through the point P.
Answer the following questions:
1) Calculate the distance OP
2) Hence write down the equation of the circle
3) Calculate the equation of the tangent line QR
4) The tangent line cuts the x-axis at point Q. Calculate the coordinates of point Q
5) Calculate the area of triangle OPQ to 1 d.p.
