Answer 1

OA is what?

Diameter? radius? or something else?

Answer 2

OA is something else for sure..
I picked the wrong one.


BO or OB is the radius of BC or CB

BC or CB is the diameter.

Answer 3

O is the center

A is a point on the circle

Answer 4

OA is a radius because of this

Answer 5

Same reasoning for OB

Answer 6

oh I didn't see your answer choice of choice D

Amy does indeed walk along the diameter BC
Frank walks along the distance OA (which is the radius)

So your answer is correct
