Question

A solid cone of height 24 cm and radius of its base 8 cm is melted to form a solid cylinder of radius 6 cm and height 6 cm.In the whole process what percent of material is wasted?

Answer 1

hieght = h = 24cm

radius = r = 8cm 

volume = v = ?

v = πr²h/3

v = π(8)²×24/3

v = π(64)(8)

v = 512π cm³
