Answer :

Diameter of cylinder = 28 cm


Radius of cylinder, R = 14 cm


Height of cylinder, H = 20 cm


Volume of cylinder, VC = πR2H



Height of cone, h = 14 cm


Radius of cone = r



Now, as the sand in cylinder forms the cone,


V = v





r = 28.98 cm


Base area = πr2



Base area = 2640 sq. cm


The base area of the cone formed is 2640 sq. cm
