Question

A hollow sphere of internal and external radii 6 cm and 8 cm respectively is melted and recast into small cones of base radius 2 cm and height 8 cm. Find the number of cones.

KnowledgeBoat · Accepted Answer

Given, External radii of hollow sphere (R) = 8 cm Internal radii of hollow sphere (r) = 6 cm Radius of cone (r₁) = 2 cm Height of cone (h) = 8 cm. Let no. of cones formed after melting sphere be n. ∴ Volume of hollow sphere = n × Volume of cone Hence, no. of cones formed = 37.
