What is the centre of rotation of the semicircle

Answer 1

Answer:

Heyaa♡♡

Here is the answer :-

Centre of the semicircle is the centre of rotation. The order of rotation of a semi-circle is 1 as when we rotate it from 0° to 360° we get the exact image of semi-circle only once i.e., when it has been rotated at an angle of 360°.

Hope it helped you.
