Question 1

Match the equations for two spheres with the SQUARE of the distance between their two centers:
I.7125A. (x+30)2 + (y+20)2 + (z-10)2 = 900 and x2 + (y+40)2 + (z-50)2 = 1600
II.6100B. (x-20)2 + (y-30)2 + (z-10)2 = 100 and (x-50)2 + (y+40)2 + (z-30)2 = 2500
III.6200C. (x+15)2 + (y-25)2 + (z-5)2 = 1000 and (x-35)2 + (y-45)2 + (z-25)2 = 400
IV.1200D. (x+10)2 + (y-40)2 + (z-20)2 = 4500 and (x-40)2 + (y-50)2 + (z-10)2 = 1600
V.2700E. x2 + (y+20)2 + (z-40)2 = 3000 and (x-25)2 + (y-60)2 + (z-30)2 = 6400
