Answer:
14π in
Step-by-step explanation:
Circumference of a circle is 2πr, and since AB is 14(the diameter), splitting that in half gets 7 (the radius). Plug that into the equation and you get:
2*7*π=C
14π=C
15$+0.5*m =
25$+0.25*m =
for the civic we get 15.50 for the first mile
for the ford we get 25.25 for the first mile
if we are to use this knowledge then brute force it we end up with 40 miles
