A sphere of diameter 12 cm, is dropped in a right circular cylinder vessel, partly filled with water.
If the sphere is completely submerged in water, the water level in the cylinder vessel rises by cm. Find the diameter of the cylindrical vessel.
Diameter of sphere = 12 cm
radius of sphere = 12/2 = 6 cm
increase in height in cyclinder vessel (H) = = 32/9
Let the radius of cylinder = R
Rise in volume in water in cyclinder is equal to volume of the sphere
