A cylindrical tank of capacity 64π litres has equal height and radius. What would be the radius of the cylinder? (1 litre = 1000 cm3)

5 cm 40 cm 50 cm 4 cm

40 cm

We know that, Volume of the tank = π r2 h  We have, Capacity of a cylindrical tank = 64π  We also know, Height of tank = Radius of tank Volume =  = 64000 π = πr3 As we know, 1litre = 1000 cm3 = 64000  =  r3 = r = 40 cm
