How many trips can a truck with a 1 by 2 meter cylindrical tank take to fill a 890,000 liters tank?

Tank diameter = 1m

radius = 0.5m

height = 2m

Volume of tank of truck = πr²h = 3.142 * 0.5² * 2 = 1.571m³ = 1571 litre

Volume of tank to be filled = 890,000 litre

no. of trips = 890000/1571 = 566.52 ≈ 567 trips
