Question

how do you tackle this question?
Determine the radius of the circle that passes through 0, 2i and 10 + 10i.

Answer 1

Well, you have 3 points, should be doable....

Answer 2

find the distance between the two points..,
then you'll find the diameter of the circle, the radius is half of diameter

Answer 3

you can start by forgetting about complex numbers and finding the center and radius of the circle that travels through the points \((0,0), (0,2), (10,10)\)
