Answer :

Diameter of internal surface =10 cm

∴ Radius of internal surface cm =5 cm

Diameter of external surface =6 cm

∴ Radius of external surface cm =3 cm

Volume of spherical shell hollow =

Height of solid cylinder cm

Let the radius of the solid cylinder be ‘r’ cm

Volume of the solid cylinder

Volume of the solid cylinder = Volume of spherical shell hollow

⇒ r^{2} × (8/3) = (4/3) × 98

⇒ r = 7

Diameter of cylinder = 14 cm
