A cylindrical tank of capacity 64π litres has equal height and radius. What would be the radius of the cylinder? (1 litre = 1000 cm3)
Answer & explanation
Correct answer: option 2
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
