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

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
 
 the top of the minute hand moves 8.38 inches

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
