1 Answer

Answer :

Height of the cylindrical vessel (h) = 25 cm  Let r cm be the radius of the base of the cylindrical vessel.  Circumference of the base = 2 πr = 132 cm ⇒ 2 x 22/7 x r = 132 ⇒ r = 132 x 7/2 x 22  = 21 cm Volume of the cylindrical vessel =  πr2h = 22/7 x 21 x 21 x 25 = 34650 cm3 ∴  Volume of water which vessel can hold =   34650 L/  1000 L = 34.65 L
