The base radii of two cones are in the ratio 3:5 and their heights are in the ratio 2 : 3. What is the ratio of their volumes? |
|
Answer» r1 : r2 = 3 : 5 h1 : h2 = 2 : 3 Ratio of the volumes \(=\frac{1}{3}\pi \times3^2\times2:\frac{1}{3}\pi \times5^2\times3\) \(=\frac{1}{3}\pi\times9\times2:\frac{1}{3}\pi\times25\times3\) = 18 : 75 = 6 : 25 |
