Question

A cylindrical water tank is of base diameter 7m and height 2.1 m find the capacity of the tank in litres

Answer 1

Answer:

80850

Step-by-step explanation:

Diameter = 7m, so Radius = 3.5m

Height = 2.1 m

Volume of cylinder = πr^2h

                                = (22/7) x (3.5)^2 x 2.1

                                = 80.850 m^3

Capacity for 1 m^3 = 1000 l

Capacity for 80.850m^3 = 80.850 x 1000

                                         = 80850 l

Thus the capacity of the cylindrical tank is 80850 litres.
