Diameter=7cm
Radius =3. 5cm
Perimeter= πr+2r
= (22/7)×3.5 + 7
=11+7
=18cm.
Please correct me if I'm wrong

shaurya18: Which formula have you used.

NikhitaDreamer: Formula of the perimeter of a semicircle is πr without the base.... but a protractor has a base that is the diameter so the perimeter is πr+2r

shaurya18: Thank you.

NikhitaDreamer: Mark this as the brainliest answer

shaurya18: Ok
