Dear Student,
COM of the cone =C1=(0,R/3)
COM of the hemisphere =C2=(0,3R/8)
Volume of the cone=V1= πR
3/3
Volume of the hemisphere=V2=2πR
3/3
COM on the y-axis of the system
=(C1V1+C2V2)/(V1+V2)
=((R/3 x πR
3/3)+(3R/8 x 2πR
3/3))/( πR
3/3+2πR
3/3)
=13R/36
Common centre on y axis=R
Distance from the common centre=R-13R/36
=23R/36
Cheers!!
