3 The diagram shows the triangle OCD with OC = OD = 17 cm and CD= 30 cm. The mid-point
of CD is M. With centre M, a semicircular arc A2 is
drawn on CD as diameter. With centre O and
radius 17 cm, a circular arc A, is drawn from C to
D. The shaded region R is bounded by the arcs A,
and A2. Calculate, giving answers to 2 decimal
places:
a The area of the triangle OCD.
b The angle COD in radians.
c The area of the shaded region R.
