Answer:

≈ 3927 litres

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = Ah ( A is the area of the base and h the height )

Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )

V = πr²h

   = π × 100² × 125 = 1250000π cm³ ( divide by 1000 )

   = \frac{1250000\pi }{1000} = 1250π litres ≈ 3927 litres ( to the nearest litre )
