The radius of the base of a cylindrical tank is 0.4 m and its height is 0.8 m. How many litres of oil will the tank hold?

(π = 3.14, 1 litre = 1000 cu cm)

Let the base radius be ‘r’ and height be ‘h’ and diameter be ‘d’

⇒ Given that ∴ r = 0.4m = 40 cm

and h = 0.8m = 80 cm

⇒ Volume of cylinder V= Area of circle at bottom × height

V=401.92 litres

The tank can hold 401.92 litres
