How To Calculate Volume Of Hollow Column:
Given,
h = 4 m.
R = 0.8 m.
r = 0.4 m.
Where
h = Height of the hollow column.
R = Centre to the outer radius of the hollow column.
r = Centre to the internal radius of the hollow column.
The formula for calculating the volume of hollow column is given below:
Volume = (πR²h – πr²h)
= πh ( R² – r²)
= 3.14 x 4 ( 0.8² – 0.4²) [∵ π =3.14]
= 12.56 ( 0.64 – 0.16)
= 12.56 x 0.48
= 6.028 m³.
This is so helpful and I am learning so many things from here.
