The ratio between the curved surface and total surface of a cylinder is 1 :2. Find the volume of the cylinder, given that its total surface area is 616 cm2. |
| Answer» <p>Given, csa :tsa of cylinder = 1:2 2πrh/2πr(r+h) = 1/2 h/(r+h) = 1/2by cross multiplication, we get 2h = r+h 2h-h = rtherefore h=rby calculating, we get height is equal to radius. then ratio of their height andradius is height of cylinder : radius of cylinder = 1:1</p> | |
