The area of the front face of the analog clock shown below is 153.86 square inches. The length of the minute hand is 0.2 inches less than the radius of the front face. What is the length of the arc, rounded to the nearest hundredth of an inch, the minute hand makes when it moves from the number 8 to the number 2 on the clock? http://learn.flvs.net/webdav/assessment_images/educator_geometry_v14/pool_Geom_3641_0810_12/image0044e68c4f6.jpg

153. 86 = pi r^2 r = \[\sqrt{153.86/\pi}\]

then, minus 0.2 inches from the radius to have the length of the minute hand the minute hand will move through 180 degrees / pi radians when it moves from 8 to 2 the arc length will be half the circumference of the circle with radius of the minute hand..... hope this will work
