Question 1136326
Find the equation of the sphere with diameter endpoints (2,-7,-2) and (-4,3,2).
----------------------
d^2 = diffx^2 + diffy^2 + diffz^2 = 36 + 100 + 16 = 152
r^2 = d^2/4 = 38
--------------
The center is ((2-4)/2,(-7+3)/2,(-2-2)/2) --- (x,y,z)
--> (-1,-2,0)
================================
{{{(x+1)^2 + (y+2)^2 + z^2 = 38}}}
