A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2

Answer:
If all other factors are controlled, and the only variable being changed is the new medication, then Byron can conclude that the new medication is effective at reducing coughing. This can be further tested by repeated experiments by peers.
Step-by-step explanation:
Hi there
Annual yield=annual interest÷bond cost
Annual interest=1,000×0.06=60
Bond cost=1,000×0.805=805
So
Annual yield=60÷805=0.0745×100
=7.45%
Good luck!
