Length of minute hand is 5.4 cm, distance covered by it in 10 mins??

• Lenght of minute hand
  = lenght of arc
  = n/360 *2*pi*r
  =60/360 *2 * 22/7 * 5.4
  =5.65cm

• the area of the entire clock is (pi*r^2=pi*(5.4)^2)
  the area covered in 10 minutes is 10/60 = 1/6 of this
  therefore, the area is pi*5.4^2/6 cm^2

• The distance covered by sector is: (angle/360)*2*pi*r
  When the minute hand cover 10 min the angle will be 60 degree
  So, the are will be
  (60/360)*2*pi*r
