A hemispherical bowl of internal radius 9 cm is full of water. Its contents are emptied into a cylindrical vessel of internal radius 6 cm. Find the height of water in the cylindrical vessel. (CBSE 2012)

Given,


Internal radius of hemispherical bowl (r1) = 9 cm


Internal radius of cyclical vessel (r2) = 6 cm


Let the height of water in the cylindrical vessel be h.


So,


Volume of hemispherical bowl = volume of cylindrical vessel






h = 13.5 cm


Hence, height of water in the cylindrical vessel is 13.5 cm
