Q. If the circumference of a circle is 200 units, Then what will the length of the arc described by an angle of 20 degree ?

• length of arc =(theta/360 degree)*(2*pi*r)
  =(20/360)*200=11.111 units

• The angle formed by a circle is 360 degrees.
  For 360 degrees --> 200 Units
  For 1 degree --> 200/360 Units
  For 20 degrees --> 200 * 20 / 360 --> 11.11 Units.
  
  So, the length of the arc described by 20 degree angle is 11.11 units.

• (20/360)*200=11.1111 units

• circumference =2*pi*r
  length of arc=(theta/360)*2*pi*r
  length=100/9

• length of arc= n/360* 2*3.14*r= 20/360*200= 11.11 radians

• length of arc= n/360* 2yr

• circumference c =200
  radius of a circle=(2*pi)/c=0.03141
  length of the arc=(theta/360)*(2*pi*r)=0.01096622771123216

• 2piR=200unit
  R=100/pi
  now
  length of arc=2*pi*100/pi*20/360
  arc=100/9 unit

• we know,
  theta=length of arc/radius of the circle(in radian)
  so,
  20 is in degree
  so 20*pi/180 in redian
  so length of arc= 20*pi*100/(180*pi)=11.1111units
