Question

A cylindrical tank is half full oil. The cylinder has a base radius of 100cm and the height of the cylinder is 250cm

Answer 1

Step-by-step explanation:

given -

1. radius of the cylindrical tank = 100cm
2. height of the cylindrical tank = 250cm
3. the tank is half full of oil

solution -

volume of cylinder = πr^2h ( take π value as 3.14 )

now put the values -

πr^2h = 3.14 × 100^2 × 250

= 3.14 × 1000 × 250

= 3,140 ×250

= 785,000 cm

now divide it by 2 as the tank is half full of oil not completely ,

therefore , 785,000÷2 =392,500 cm

now convert it into liters ,

therefore, divide 392500 by 1000

therefore final ans is 392.5 liters of oil

Answer 2

Answer:

Volume of the tank

= area of the circular face x height

= Pi x r^2 x h

= 3.14 x 100^2 x 250

=7850000 cm^3

The tank is half filled. So the volume of oil in the tank is half of the above volume.

= 3925000 cm^3

3925000÷1000

= 3925 liters.
