A cylindrical vessel of diameter 84 cm and height 18 cm contains milk. This milk is to be filled in cylindrical tumblers of radius 7 cm and height 6 cm. Find the number of tumblers that can be filled with milk.
Given: Diameter of cylindrical vessel=84 cm ⇒ radius of cylindrical vessel (R) = 42 cm
Height of cylindrical vessel (H) = 18 cm
Let V denote the volume of the cylindrical vessel.
Radius of cylindrical tumbler (r) = 7 cm
Height of cylindrical tumbler (h) = 6 cm
Let V1 denote the volume of the cylindrical tumbler.
Let ‘n’ number of tumblers can be filled.
Thus, 108 tumblers can be filled with the milk.
