```										dear shashank ,
total  area of circle = A
for 2pi rad area = A
for 1 rad area = A/2pi
for θ radian area = Aθ/2pi     =   R2θ/2  ............1                ( A = piR2 )
arc = θR          ............2
area = R2 θ = 168pi      .......3                   (given)
arc = R θ = 14pi           .......4                     (given)
solving  3 & 4  we get
θ = 7pi/12               ans
approve if u like my ans
