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

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
