Question

1. A metallic sphere of radius 4.2 cm is melted and recast into the shape of
radius 6 cm. Find the height of the cylinder
Lofradiicm 8cm and 10 cm, respectively, we means​

Answer 1

Answer:

Since sphere of radius r is melted and recast in to cylinder of radius R and height h.

So, volume of sphere =Volume of cylinder

$\frac{4}{3} \pi \: {r }^{3} = \pi \: { R}^{2} h \\ \frac{4}{3} \times 4.2 \times 4.2 \times 4.2 = 6 \times 6 \times h \\ h = \frac{1372}{1000} \\ h = 1.372 \: cm$
