Question

Line segment BD passes through the center of circle C, BH = a, and HD = 8. What is the length of the diameter?

Answer 1

D. 12.5 units

Answer 2

if the line down the center is 8 and the diaameter is in the middle then both those sides need to be 8 and so the 6's on both sides of the diameter have to stay they same but they only change a little for 6+6 is 12 but the length gets longer since it moved farther down
answer D 12.5
