Answer 2

Answer:

Circumference of semicircle is 216 m.

Step-by-step explanation:

Given:

Radius of semicircle (r)= 42 m.

Circumference of semicircle = ($\pi r+2r$)

                                               = {(22/7)×42} +(2× 42)

                                               = (22×6) +84

                                             = 132 +84=216 m.
