Question 522730
The minute hand of a clock is 11 inches long. How far does the tip of the minute hand move in 25 minutes?
================================
The distance, S, that the hand moves is the length of the arc:
S = R*{{{theta}}} where R = the radius and {{{theta}}} = the angle in radians
{{{theta}}} = 25/60*360 deg * {{{2*pi}}} rad/360 deg = {{{5*pi/6}}}
Given: R = 11 in.
Therefore the distance, S = {{{5*pi/6}}}*11 = 28.8 in.
