# A metallic solid

Given: Radius of the solid sphere = 9 cm

Radius of the cylinder = 9 cm

Volume of Solid Sphere is: × π × r3 (here r is radius of the sphere)

Volume of Solid Cylinder is: π × r2 × h (here r is radius and h is height of the cylinder)

Let v1 be the volume of given Solid Sphere.

v1 = × π × 93 cm3

Let v2 be the volume of Solid Cylinder.

v2 = π × 92 × h

We know that when a object is moulded from one shape to other its volume does not change.

v1=v2

That is,

× π × 93 = π × 92 × h

h = = = 12 cm

h = 12 cm

That is Height of the Cylinder is 12 cm
