Answer:
3927 litres of oil to the nearest litre.
Step-by-step explanation:
The volume of the cylinder = π r^2 h
= π * 100^2 * 250.
When half full the volume is Â
1/2 * π  * 100^2 * 250
= Â 3926991 cm^3 Â Â Dividing this by 1000:
= 3927 litres.
A cylindrical tank is half-full of oil.
There are 3928 liters of oil in the tank
Volume of cylinder is teh amount of material the cylinder holds. Â Volume is the density of the cylinder.
Volume Formula :
[tex]volume = \pi r^2h[/tex]
Given the radius of the cylinder is 100cm
Height of the cylinder is 250 cm
Substitute all the values inside the formula
[tex]V=\pi (100)^2(250)\\V=2500000\pi[/tex]
Cylinder tank is half full of oil . To find half of the volume , we divide the volume by 2
[tex]V=2500000\pi\\Half - full = \frac{2500000}{2}\pi \\Half-full =3926990.817 cm^3[/tex]
Given that 1 litre= 1000cm^3
convert cubic centimeter to litres
[tex]1000cm^3= 1litre \\3926990.817 cm^3=\frac{3926990.817 }{1000} \\1250000 cm^3=3927.99 liters[/tex]
There are 3928 liters of oil in the tank
