Diameter Wheel

Diameter Wheel
how many times do wheels turn per minute walking at 3.5 mph and a 4 in diameter wheel?

can someone do the math?

Circumference (C) of the wheel is:
C = 4*3.2426 = 12.57 in
So 1 revolution is 12.57 inches

Convert mile to inches
3.5 miles * 5280ft/mile * 12in/ft = 221,760 in

Number of revolution (R) is

R = 221,760/12.57 = 17642 turns

There is a typo
PI = 3.1416 but I entered 3.2426 but when I did the calculation I entered the correct value so the result is still right…lol
