Answer:

The unicycle will travel 351.68 inches in 7 revolutions

Explanation:

The circular shape moves a distance equal to its circumference in each revolution, then the rule of the distance of the circular shape travels n turns is D = π d n, where

  • d is the diameter of the circular shape
  • n the number of revolution

∵ A unicycle wheel has a diameter of 16 inches

d = 16 inches

∵ The unicycle will travel 7 revolutions

n = 7

→ Substitute them in the rule of the distance above

D = π(16)(7)

∵ π = 3.14

∴ D = 3.14(16)(7)

D = 351.68 inches

→ No need to round it, it is in the hundredth of an inch

The unicycle will travel 351.68 inches in 7 revolutions
