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

Volume of Cylinder = Volume of Cone

$\pi \: r {}^{2} h \: = \pi \: r {}^{2} h \div 3$

Hence there radius is same so we get

h = h / 3

3h = h

height of cylinder is 5cm kn putting value

3 × 5 = h

h = 15cm
