Two cylinders have their radii 4:5 and their height is 5:6 find the ratio of their curved surfacepls do it |
|
Answer» height=5y Curved surface area = 2*pi*r*h =2*pi*4x*5y Case 2 radius=5X height=6y Curved surface area = 2*pi*5x*6y Case1/Case2 = 2*pi*4x*5y/2*pi*5x*6y ( SIMPLIFICATION = cancel 2 to 2 and pi to pi and X to x and y to y) =4*5/5*6 20/30 ( simplification ) 2: 3 |
