Question

A minute-hand is 16 in long. Find the distance traveled by the tip of the minute-hand in one hour.

Answer 1

Circumference = $d \pi$

$16 \pi = 50.27$

The minute-hand traveled 50 inches in one hour.

Answer 2

consider the length of the minute hand the radius of a circle

 the diameter would be 16*2 = 32 inches

 circumference ( distance around the circle) =

PI *32

using 3.14 for PI

3.14 *32 = 100.48 inches  Round the answer as needed
