Question

A certain no of metallic cones each of radius 2 cm and height 3 cm are melted and recast in a solid sphere of radius 6 cm.Find the number of cones

Answer 1

volume of metallic cones of radius 2cm
= 1/3(π ×2 ×2 ×3)
= 4π cubic cm

volume of solid sphere of radius 6cm
=4/3(π×6×6×6)
=288π cubic cm

no. of cones = (volume of one sphere) / (volume of one cone)

no. of cones = 288π / 4π
no. of cones = 72 cones. Ans.
