Question

a solid mettalic cylinder of radius3cm and height 5cm is melted to form cones each of height 1cm and base radius 1mm. find the number of cones

Answer 1

volume of cylinder = X * volume of cone
pi r2 h = X * 1/3 pi r2 h
3 * 3 * 5 = X * 1/3 * 0.1 * 0.1 * 1
45 = X * 1/300
45 * 300 = X
13500 = X ( number of cones )

Answer 2

So the number of cones=13500
