Question

The dimension of solid iron cuboid are 4.4 metre into 2.6 metre into 1.0 m it is melted and recast into a hollow cylindrical pipe of 30 cm in radius and thickness 5 cm find the length of the pipe

Answer 1

Answer:

H=40.481245577m

Step-by-step explanation:

It is given that solid sphere is melted in hollow cylinder means both will have equal volume

therefore,

lbh=πr^2h

putting all values we get

h=40.481245577m
