Well maybe you need to redo the question
Step-by-step explanation:

Answer:
B. AD = sqrt(CD * BD)
Step-by-step explanation:
By the right triangle altitude theorem,
CD/AD = AD/BD
AD^2 = CD * BD
AD = sqrt(CD * BD)
Answer: B. AD = sqrt(CD * BD)
A: a flow chart would best describe the steps
Step-by-step explanation:
We have given that,
The inner radius of a bicycle wheel is 12 inches.
