Answer:
A. 9.3 units
Step-by-step explanation:
line CR and CV are radius of the circle, therefore CR = CV
the length from C to the Mid chord is the same for VI and RA, i.e
CVI = CRA = 4.7 units
the radius CR for chord RA is 6.6 units, gotten using phythagoras theorem
since the radius and 4.7 unit are the same, therefore
the chord length VI = RA = 9.3 units
