Question 464112
Sketch a circle with the endpoints for its diameter at (5,9) (11,17)
-------------------
The center is the midpoint.
C: x = (5+11)/2 = 8
y = (9+17)/2 = 13
Center @ (8,13)
---------------------
radius = distance from center to (5,8)
{{{radius = sqrt((13-9)^2 + (8-5)^2) = 5}}}
--> {{{(x-8)^2 + (y-13)^2 = 25}}}
