Hey, Centre of mass is the point at which the entire mass of the body is said to be concentrated. It may or may not lie inside the body area. For eg, a square has its CM at its intersection of diagonals. Moreover, u can also express it as the point at which the body is symmetrical atleast about one axis. For a triangle, its the centroid....
So use the summation formulae of CM and get started....

Center of mass, is a point, lying inside or outside a body, where the whole mass of the system is assumed to be concentrated.

The centre of mass (/gravity) of a body or a system of particles is the resultant of the weights of the individual particles making up the body or system.

The centre of mass of a uniform semicircular lamina of radius r lies on the axis of symmetry at a distance of 4r/3p from the straight edge
A lamina is a 2-dimensional object. In other words, it is a flat object whose thickness is we can ignore.

The centre of mass of a uniform solid hemisphere of radius r lies on the axis of symmetry at a distance of 3r/8 from the base
