Question

A metalic right circulation cylinder of radius 6 cm and height 14 cm is melted and recast into 3 spheres. If the radii of the two spheres are 2 and 3 find the third

Answer 1

Answer:

7cm

step by step explanation:

vol. of cylinder = 22/7 *6^2*14 = 1584

vol. of 3 spheres

4/3 *22/7 *(2^3+3^3+r^3) = 1584

r^3 = 343 => r = 7 cm
