The radius of two cylinder are in the ratio 2 ratio 3 and their height are in the ratio 5 ratio 3 calculate the ratio of their curved surface areas |
|
Answer» their CURVED surface AREA is in the RATIO 10:9Explanation:r1/r2=2/3 h1/h2=5/3 curved surface area = 2πrhhence its ratio WOULD be 2πr1h1/2πr2h2=r1h1/r2h2=r1/r2*h1/h2=2/3*5*3=10/9hence ratio= 10:9 |
