Question

a metallic sphere of radius 4.2 centimetre is melted and recast into the shape of a cylinder of radius 6 cm find the height of the cylinder

Answer 1

Answer:

For sphere

r=4.2 cm

For cylinder

r=6

h=?

Here volume of sphere=volume of cylinder

4/3πr×r×r=πr×r×h

4/3×4.2=h

4×1.3=h

h=5.2
