sudhanshu divides a circular disc of radius 7 cm in two equal parts. what is the perimeter of each semicircular shape disc? (pi-22/7)

formula for perimeter of a circle = 22/7 x diameter
therefore , 22/7 x 7+7 = 22/7 x 14 = 44/2 = 22 ( divided by two cuz we want the perimeter of half the circular disc)
So,
= The perimerter of each of the half of the circular disc is 22
