5 A circle with centre \(C\) has equation \(( x + 3 ) ^ { 2 } + ( y - 2 ) ^ { 2 } = 25\).
- Write down:
- the coordinates of \(C\);
- the radius of the circle.
- Verify that the point \(N ( 0 , - 2 )\) lies on the circle.
- Sketch the circle.
- Find an equation of the normal to the circle at the point \(N\).
- The point \(P\) has coordinates (2, 6).
- Find the distance \(P C\), leaving your answer in surd form.
- Find the length of a tangent drawn from \(P\) to the circle.
