Find the perimeter of semi circle ​

Answer» ONG>Answer:

88cm

Step-by-step explanation:

if we draw the circles by TAKING the side of the square as diameter, we get 4 circles HALF of each inside the square and half outside of the square.

the perimeter of the figure = perimeter of 4 semi-circles

 the perimeter of a semi-circle = 2πr/2= πr

 the perimeter of 4 semi-circles  = 4×πr

the perimeter of the figure =  4 ×(22/7)×7= 88cm
