Solution :-
Let the radius be 3x and height be 2x
As we know that
→ Volume of cylinder = πr²h
Where ” r ” is radius, ” h ” is height of a cylinder
According to question
→ Volume of cylinder = 19404
→ πr²h = 19404
→ 22/7 × (3x)² × 2x = 19404
→ 22/7 × 9x² × 2x = 19404
→ 22/7 × 18x³ = 19404
→ 22 × 18x³ = 19404 × 7
→ 396x³ = 135828
→ x³ = 135828/396
→ x³ = 343
→ x = ∛343
→ x = 7
Hence,
