Question

Find the circumference of the tire.
About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answer 1

a) Circumference = 2πr
= 2π(2.5 ft)
= 15.71 ft

b) Circumference of tire = 15.71 ft
Distance traveled in 1 mile = 5,280 ft

Number of times tire must rotate = 5,280 ft / 15.71 ft
= 335.6 times

Answer 2

AAAaannndd the bot gets it wrong yet again!

C = πd
5280/(2.5π) = 672.27
