Question

If the diameter of a circle has endpoints at (-2,4) and (3,8), what is the length of the radius of the circle?

Answer 1

you have to find the midpoint of these two points

Answer 2

the diameter will be root 37 so the radius is root 37 by2

Answer 3

by distance formula..

Answer 4

So the answer is about 12?

Answer 5

I got the diameter to be \(\sqrt{41}\), using the distance formula \(\sqrt{(-2-3)^{2}+(4-8)^{2}}\), which would give a radius of half that (about \(3.2\))
