Explanation / Answer

Solution:(58)

s = r (measured in radians)
   = 17m * 80 * (pi/180)
   =68pi/9 m
   =23.74 m

Solution:(59)

Circumference = 2pi*r = 2pi*4 = 8pi

So,

5/8pi = /2pi

= 10pi/8pi = 5/4 radians

now

pi radians = 180 degree

So,

= 5/4 radians = (5/4) * (180/pi)

   = 225/pi

= 71.6 degree
