If the minute hand is 6 inches long, that means the radius of the circle it forms is 6 inches. the circumference of a circle is found by C = 2*Pi*r. Filling in 6 for r and3.14 for Pi, we get
C = 2 * 3.14*6 = 37.68 inches. This is the distance the whole way around the circle.
a) 15 minutes out of 60 is 15/60 = 1/4 of the circle. The distance it travels in 15 minutes is 1/4 x 37.68 or 9.42 inches.
b) 25 minutes out of 60 is 25/60 = 5/12 of the circle. The distance it travels in 25 minutes is 5/12 x 37.68 or 15.7 inches.
I hope that helps!!

The far does the tip of the minute hand move is 7.85714 inches.
Given that,
- The minute hand of a clock is 3 inches long
- And, the given time period is 25 minutes.
Based on the above information, the calculation is as follows:
[tex]= \frac{25}{60} \times 2\pi \times r\\\\= \frac{25}{60} \times 2\pi \times 3\\\\= 2.5 \times \frac{22}{7}[/tex]
= 7.85714 inches
Therefore we can conclude that the far does the tip of the minute hand move is 7.85714 inches.
