A cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 H
Softa [21]

Answer:

V=3926.99 liters

Step-by-step explanation:

cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?

Volume of a cylinder can be calculated using below formula

V=π r^2 h

Where r= radius

h= height

radius = 100 cm

h=250cm

But the cylinder is half filled, then the formula becomes

V=(π r^2 h) × 1/2

Then substitute the values we have

V=( π × 100^2 ×250) × 1/2

V=3926990 cm^3

But 1 litres = 1000cm3

Then V=(3926990 cm^3)/ 1000

V=3926.99 liters
