How far does the tip of the minute hand of a clock move in 35 minutes if the hand is 4 inches long?

Q:
How far does the tip of the minute hand of a clock move in 35 minutes if the hand is 4 inches long?
Accepted Solution
A:
It moves 14.66 in.
Explanation:
The distance around an entire clock is the circumference of a circle. Circumference is given by the formula C=Ο*d.
Since the minute hand is 4 inches, this is the radius; the diameter would be 4*2=8.
The circumference would then be C=3.14*8 = 25.12 inches.
A clock is broken into 60 minutes; 35 minutes is the fraction 35/60. Multiply this by the circumference of the entire clock: 25.12(35/60) = 14.66.
