CIRCUMFERENCE OF CIRLCE = 2πr
CIRCUMFERENCE OF SEMICIRCLE = 2πr × 1/2
                                                             = πr
                                                             = 22/7 × 3.85
                                                             = 22 × 0.55 
                                                             = 12.1 cm

Circumference of semi.circle = 12.1 cm
