Question

a cuboid with length 14cm and breadth 11 CM and a cylinder have the same height and volume. The radius of the base of the cylinder is

Answer 1

We have,length, l = 14 cmbreadth, b = 11 cmLet the height = hVolume = lbh = 154h cm3Now, height of the cylinder = hLet r be the radius of base of cylinder.Now, volume of cylinder = πr2hAccording to question : πr2h = 154h⇒227r2 = 154⇒r2 = 154×722 = 49⇒r = 7So, radius of base of cylinder = 7 cm
