When we melt any shape, and recast into another shape than volume of both shapes remain same.

Radius of the circular cone (r1) = 1.6cm

Height of the circular cone (h1) = 3.6cm

Radius of the new circular cone (r2) = 1.2 cm

Let height of the new circular cone be h2

Volume of the circular cone = volume of the new circular cone

(1.6)2 × (3.6) = (1.2)2 × h2

h2 = 64 cm

So, the height of the new circular cone will be 64cm
