Points (–12, 1) and (2, 3) are endpoints of the diameter of a circle.
(a) What is the length of the diameter? Give the exact answer, simplified as much as possible.
Show work. answer:: length = sqrt[(3-1)^2+(2+12)^2] = sqrt[4+14^2] = sqrt(200)
= 10*sqrt(2) = 14.14..
----------------------------
(b) What is the center point C of the circle?
answer:: x = (-12+2)/2 = -5 ; y = (1+3)/2 = 2
Ans::(-5,2)
---------------------------------------
(c) Given the point C you found in part (b),
state the point symmetric to C about the x-axis.:: (-5,-2)
