Answer:
A (first picture)
Step-by-step explanation:
Based on the picture, the lines are both perpendicular and the red line splits AB into two equal parts (bisects it), so it must represent the perpendicular bisector of AB.
1/7 = 3/4x-1
3/4x=1/7+1=8/7
x=8/7*4/3=32/21
16 pi? well... 16 pi = 50.2654824574. So... the diameter would be 16 and the radius would be 8. I think!
