Question

The minute hand of a clock is 8 inches long and moves from 12 to 2 o'clock how far does the top of the minute hand move? express your answer in temrs of pie and then round to two-decimal places

Answer 1

The perimeter in 60 minutes is:
2 * pi * r
2 * pi * 8
50.26548246 inches
It moves from 12 to 2:
The perimeter will be:
(10/60) * (50.26548246)
Rewriting:
= (2/12) * (50.26548246)
= (1/6) * (50.26548246)
= 8.37758041
round to two-decimal places:
= 8.38 inches
Answer:
the top of the minute hand moves 8.38 inches
