Why rainbow looks semi-circular?

Answer» because we can see the light rays of primary rainbow which comes at angles of43° to 45°. such rays can come only from a circular belt of rain drops.and rays of secondary rainbow make 52° to 55°.
Actually it is not semi circle it is a circle but v can see a half because v live in one himesphere It is is circle because the rain drops which scatter r epual distane from us if u know the rule of formation of rainbow then u can understand my point
Due to dispersion of light
