What is the distance of centre of mass of a half fring from centre if the ring has radius `=0.5` m [XI]

Consider a system of two spheres of masses 5 kg and 25 kg. The distance between their centres is 1.2 m. What is the distance of their centre of mass from the centre of the sphere of mass 5 g?

The distance of the centre of mass of a hemispherical shell of radius R from its centre is

Two semicircular rings of linear mass densities lamda and 2 lamda and of radius 'R' each are joined to form a complete ring. The distance of the centre of the mass of complete ring from its geometrical centre is :
