Hello there. I'm currently studying AS level maths in the UK and have been given a sheet of circle questions (This is not my strong point either).
I'm hoping you can help with this .
1) A circle passes through the points (2,0) and (8,0) and has the y axis as a tangent. Find the two possible equations.
2) A(6,3) and B(10,1) are two points on a circle with centre (11,8).
Part 1 - the co-ordinates of the mid-point of the chord
Part 2 - the disbance of the chord AB from the centre of the circle
Part 3 - the radius of the circle.
Thanks a lot for your time and help, please
