Question

An aluminium sphere of radius 12cm melted to make a cylinder of radius 8cm.find the height of the cylinder

Answer 1

Step-by-step explanation:

radius of sphere = 12 cm

given it is melted to form cylinder of radius 8cm

so volume of sphere = volume of cylinder

4/3πr^3=1/3πr^2h

4/3x12x12x12=1/3x8x8xh

2304=64/3xh

h=2304x3/64

h=108cm

hence height of cylinder is 108cm
