Solution

Solution:

If the minute hand is 14 inches long, that means the radius of the circle it forms is 14 inches.

The circumference of a circle is found by C = 2r.

we get

C = 2 * * 14 = 87.96 inches. This is the distance the whole way around the circle.

21 minutes out of 60 is 21/60 = 7/20 of the circle. The distance it travels in 21 minutes is

= 7/20 x 87.96 = 30.786 inches
