Question

a hamster wheel has a 7 inch diameter. How many feet will a hamster travel in 100 revolutions of the wheel?

Answer 1

1 revolution = pi * diameter
= 3.14 * 7 inch
100 revolution
= 100 * 3.14 * 7 = 2198 inches
= 2198 / 12
= 183.17 feet

Answer 2

1 revolution = circumference of the wheel = pi * diameter

= 3.14 * 7 inch

so 100 revolution = 100 * 3.14 * 7 = 2198 inches

= 2198 / 12 = 183.17 feet
