I.

r = 1.732

A. farthest vertex (20,60,-50)

II.

r = 30

B. farthest vertex (0,-20,0)

III.

r = 67.823

C. farthest vertex (30,70,30)

IV.

r = 70

D. farthest vertex (15,25,35)

V.

r = 66.895

E. farthest vertex (11,41,-31)

Question 2

Match the equation of the circle with its correct center and radius:

I.

r=10, (20,50)

A. (x+40)2 + (y-30)2 = 2500

II.

r=30, (-20,30)

B. (x-20)2 + (y-50)2 = 100

III.

r=60, (-25,-25)

C. (x+20)2 + (y-30)2 = 900

IV.

r=20, (-80,10)

D. (x+25)2 + (y+25)2 = 3600

V.

r=50, (-40, 30)

E. (x+80)2 + (y-10)2 = 400
