Question

Find the equation of a circle given that the points (8,0) and (0,6) are endpoints of a diameter

Answer 1

Using the midpoint formula I know that part of the equation is:
(x-4)^2 + (y-3)^2 =r^2 but I don't know r

Answer 2

find the length of the diameter
= sqrt((6-0)^2 + (0-8)^2)
and radius is 1/2 of this

Answer 3

D would equal 10, so the radius would be 5 not .5 though?

Answer 4

correct - 5

Answer 5

5

Answer 6

Oh, yes thought you were saying the radius was 1/2. Thank you
