See attachment.

Angle MCL = beta/2

Angle LOB = 90 -beta/2

HI = radius*sin(90-beta/2) = 0.5*cos(beta/2)

GH = GI - HI

GI = A - FG = 3 - 1.0625 = 1.9375

=> GH = ML = GI - HI = 1.9375 - 0.5*cos(beta/2)

JM = 0.5*cos(90-beta/2) = 0.5*sin(beta/2)

MK = radius - JM = 0.5 - 0.5*sin(beta/2)

MC = KC - MK

KC = ...
