Question

A cone was melted and cast into a cylinder of the same radius as that of the base of the cone. If the height of the cylinder is 5 cm, find the height of the cone??! answer is 15 cm..but how?steps plz..fast plz

Answer 1

Answer:

according to question

radius of cone = radius of cylinder

volume of cone= volume of cylinder

1/3 pi radius of cone ² height of cone

1/3 pi radius of cone ² height of cone= pi radius of cylinder ² height of cylinder

1/3 x height of cone = height of cylinder

1/3 x height of cone = height of cylinder1/3 x height of cone = 5

1/3 x height of cone = height of cylinder1/3 x height of cone = 5thus the height of cone is 15 cm

hope this will help you
