Given: Radius of radii of two cylinder = 5 : 4 Ratio of heights of two cylinder = 2 : 3 Formula: Volume of cylinder = πr2h Calculation:Let r1=5,r2=4,h1=2 and h2=3 Volume of first cylinder V1=π(r1)2×h1 Volume of second cylinder V2=π(r2)2×h2 According to the question V1:V2=π(r1)2×h1:π(r2)2×h2 ⇒ V1:V2=52×2:42×3 ⇒ V1:V2=25×2:16×3 ⇒ V1:V2=25:24
