The height of a conical vessel is 3.5 cm. If its capacity is 3.3 litres of milk. Find the diameter of its base.
We have
Height of conical vessel = 3.5 cm
Volume = 3.3 litre = 3300 cm3
= 1/3πr2h = 3300
=r2 = 3300×3×7 / 22×3.5 = 900
= r =√900 = 30 cm
Hence diameter of its base = 2× radius = 2×30 = 60 cm
