In this article we have discussed about calculate the volume of a circular column. To calculate volume of circular column here is the formula.
Volume of circular column V = π × r² × h
Where V = volume of circular column
r = radius of circular column
h = height of column
So, this is formula to calculate volume of circular column.
Now, we are understand using example.
Step:1: Collect data:
Diameter of column = 300 mm
Height of column = 3 m
To calculate radius of column = diameter/2 = 300/2 = 150 mm

Step: 2 Calculate the volume of circular column:
Volume of circular column =
= π × r² × h
= 3.14 x (150/100 x 150/1000) x 3 (Here π value is 3.14 & to convert mm to meter divide 1000)
= 3.14 x 0.0225 x 3
= 2.1195 cumt
So,
For 300 mm circular column volume of column is 2.1195 cumt
