What is the greatest possible distance between two points: one on a circle with radius 1
and centre (1; 2) and the other on a circle with radius 2 and centre (4; 6)
I am not familiar with the equation of a circle, is there a way to do this without using the circle equation?
Best Answer
There is a way to do this without using the circle equation, yes.
Hint: start by simplifying it. Given a point and a circle, what is the greatest possible distance between that point and a point on the circle? Then how can you use that result to solve your problem?
