Refer to the figure and match the theorem that supports the statement.
1. if chords are =, then arcs are =. if bc = de, then arc bc = arc de
2. if arcs are =, then chords are =. if ax is perpendicular to bc, then bx = xc
3. diameters perpendicular to chords bisect the chord if arc bc = arc de, then bc = de

Step-by-step explanation:

Refer to the figure and match the theorem that supports the statement.

1.If chords are =, then arcs are =.  

If BC = DE, then Arc BC = Arc DE  

2.If arcs are =, then chords are =.  

If Arc BC = Arc DE, then BC = DE  

3.Diameters perpendicular to chords bisect the chord  

If AX is perpendicular to BC, then BX = XC

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
