The total plane angle subtended by a circle at its centre is a) pi rad b)2pi rad c)2pi /3 rad d) pi/2 rad

  • The total angle subtended by a circle at its centre is equal to 360 degrees.
  • Convert 360 degrees to radians:
  • 360 * (pi / 180) = 2 pi radians
Ans: Option - (b)

  • 4
(b) 2 pi radians
Since, 180 degree = pi radians
So,      360 degree = 2 pi radians.
