mountain bike wheel has diameter of 40 inches , in how many turns will the bike be able to cover 1 km?

Question

note :
circumference of circle = pi ((radius)^2)
radius = diameter/2

Answer 1

The formula is C = pi * d

40 inches = 101.6 cm = 1.016 m

C = 3.14 * 1.016

c = 3.19024 m

1000 / 3.19024 = ________ turns

Answer 2

K THANKS , BUT WHY YOU divide 1000 /3.19024

Answer 3

You need to know how many turns the wheel made in 1 kilometer

1 km = 1000 m
