Question

A minute hand of a clock is 13 inches long. Find the distance traveled by the tip of the minute hand in one hour.

Answer 1

To find the distance the tip of the clock travelled, we can use the arc length formula, which is

$d=2\pi r(\frac{\theta}{360})$

Where r represent the radius of the clock, and θ represents the angle of the arc.

A clock have 12 hours, and a circle has 360º. If we divide 360º by 12, we're going to find the angle the hand of the clock t
