Morphology

semicircle = circle (transparent) = semi + circle

The meaning is directly compositional: 'semi-' means half and 'circle' supplies the geometric base.

Etymology

Semicircle comes from the parts semi- 'half' and circle 'round shape'. The semi- part is the same as in semifinal, so semicircle means one half of a circle, with the straight diameter across and the curved arc around it.
