Length of the minute hand is 11.25' from the center of the clock to the tip of the hand.
<u>Question asked:</u>
What is the area swept out by the minute hand as it moves 5 minutes of time?
Solution:
<u><em>As length of the minute hand is '11.25' from the center of the clock to the tip of the hand means radius of the circle, r = 11.25 inches.</em></u>
