I'm pretty ok at maths however I really get stuck on the whole circle problems and would appreciate some help
1. Part 1 - Find the mid-point, C, of AB where A is (1,8) and B is (3,14) respectively.
Part 2 - Find the distance between AC
Part 3 - Find the equation of the circle which has AB as diameter.
Thanks a lot
The distance between A and C, or the length of the line segment AC, is calculated as:
The circle with AB as diameter has center C, and its radius is the length of AC. The equation for a circle with center (h, k) and radius r is . Just plug in the numbers; you've got all of them now.
