When ‘h’ coins each of radius ‘r’ units and thickness 1 unit is stacked one upon the other, what would be the solid object you get? Also find its C.S.A. |

Answer» Thickness = 1 unit radius = r unit Number or coins = h When we stacked coins on upon the other, we get the object cylinder. Height of formed cylinder = thickness of 1 coin x Number of coins = 1 x h = h unit Radius of formed cylinder = r unit ∴ C.S.A. of formed cylinder = 2πrh unit2 |
