<PRE><B>Question 926614</B>
on the clock face 12 = 0
---
number of segments in the arc from 12 to 4?
number of segments = 4 - 12
but 12 = 0
number of segments = 4 - 0 = 4
---
the clock face is divided into 12 segments (5 minutes each)
---
what fraction of the clock circle is the arc from 12 to 4?
4/12 = 1/3
---
in one hour the tip of the minute hand traces an arc of length c = 2*pi*r
where r = 11 inches
c = 2*pi*11 = 22 * pi
---
what fraction of c is the arc from 12 to 4?
1/3 * 22 * pi
---
answer:
7.33 * pi
