The circle C has centre A (10, 12) and passes through the point B (15, 15). a) Find the length of AB, giving your answer as a simplified surd. b) Hence write down an equation for C in the form (x+c)^2 + (y+d)^2 = r^2.

a) Given two coordinate pairs (x1, y1) and (x2, y2) you can work out the distance AB as sqrt((x1-x2) 2 +(y1-y2) 2 ) - subbing in values gives us sqrt(5 2 +3 2 ) which is equal to sqrt(34) . Despite the quest...
