Sushant has a vessel, of the form of an inverted cone, open at the top, of height 11 cm and radius of top as 2.5 cm and is full of water. Metallic spherical balls each of diameter 0.5 cm are put in the vessel due to which 25th of the water in the vessel flows out. Find how many balls were put in the vessel. Sushant made the arrangement so that the water that flows out irrigates the flower beds. What value has been shown by Sushant?

According to teh question,
h = 11 cm, Radius of a conical vessel = r = 2.5 cm
radius of a metallic spherical ball = R = 0.5/2 = 0.25 cm
Let n be the number of spherical balls that were dropped in the vessel.
Volume of water spilled =  Volume of spherical balls dropped
