A cylindrical tank is half-full of oil. The cylinder has a base radius of 100 cm. The height of the cylinder is 250 cm. How many litres of oil are in the tank? 1 litre = 1000 cm3

Answer :

V=hpir²


1/2 full

Vcylinderthisone=(1/2)hpir^2
given
h=250
r=100

so

V=(1/2)(250)pi(100)²
V=125pi10000
V=1250000pi
aprox pi=3.141592
V=3926990 cm^3

divide by 1000
3926.99 liters
about 3927 liters

A cylindrical tank is half-full of oil. The cylinder has a base radius of 100 cm. The height of the cylinder is 250 cm than the oil present in the tank is 3926.990 lit.

Given :

  • The cylinder has a base radius of 100 cm.
  • The height of the cylinder is 250 cm.

The volume of the half cylinder is given by:

[tex]\rm Volume = \dfrac{1}{2}(Base\; Area \times Height)[/tex]

[tex]\rm Volume =\dfrac{1}{2} (\pi r^2)\times h[/tex]

[tex]\rm Volume =\dfrac{1}{2}\times (\pi \times (100)^2)\times 250[/tex]

Volume = 3926990.82 [tex]\rm cm^3[/tex]

Volume = 3926.990 lit.

So, 3926.990 lit. of oil are present in the cylindrical tank.
