GIVEN :

A metallic right circular cone and a metallic cylinder of height 5.4 m and 4.8 m respectively.

FORMULA USED :

Volume of cone = (1/3) × π × r2

Volume of cylinder = π × r2 × h

Volume of sphere = (4/3) × π × r3

**ASSUMPTION :**

Let ‘r’ is radius of cylinder.

CALCULATION :

According to the question,

Radius of cylinder = radius of cone = r

And, volume of cone + volume of cylinder = volume of sphere

(1/3) × π × r^{2} × 5.4 + π × r^{2} × 4.8 = (4/3) × π × 6.6 × 6.6 × 6.6
