Name: Date:The graph above shows a circle centred at the origin, O. The point P lies on the circle and has coordinates (-12, 16). 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 y-axis at point R. Calculate the coordinates of point R
5) Calculate the area of triangle OPR to 1 d.p.
