0. A horse is tethered to a stake by a rope of 30 m long. If the horse moves along the circumference of a circle keeping rope tight, find that how far the horse have gone from initial point if the rope has traced an angle of 1050 at the center?

  • Option : A
  • Explanation : (A)

    Radius = m, θ = 1050
    Length of the arc (̅AB) = (πrθ)/1800

    = 55 m
    ∴ Horse covered a distance of 55 m from initial point A to B.
