Question

A metallic sphere of radius 4.2cm is melted and recast into the shape of a cylinder of radius 6cm. Find the height of the cylinder.

Answer 1

$\bf\large\underline\pink{Answer:-}$

If a solid is recasted in any other solid the volume remains the same.

so,vol.of sphere=vol. of cylinder

•4/3πr cube= 2πr square ×h 4/3×22/7×42/10×42/10×42/10 = 2×22/7×6×6×h

h= 98.784/36

H=2.744

Answer 2

Answer:2.734cm

Step-by-step explanation:volume of cylinder=volume of sphere
