Question

A solid sphere of metal with diameter 20 cm. is melted and poured into a cylindrical vessel with diameter 30 cm. To what hieght in cm will metal rise in vessel

Answer 1

Answer:

Step-by-step explanation:

Sphere diameter = 20 cm

i.e. Radius = 10 cm

Volume of Sphere = Volume of Cylinder

$\frac{4}{3} \pi r^{3} = \pi r^{2} h\\i.e. \frac{4}{3} * 10^{3} = 15^{2} * h\\i.e. 4 * 1000 = 225 * 3 * h\\i.e. 4000 = 675 * h\\i.e. h = 5.92 cm$
