How to calculate the Volume & Surface area of Circular Column / Volume Of Concrete / Area Of Shuttering / Area Of Painting work

The following Article explain you that brief explanation of calculation of surface area & volume of circular column , surface areas used to find painting &  Shuttering areas quantity  also Volume of circular is used to find the concrete quantity

Surface Area calculation / Area Of Shuttering / Painting area for circular column

The surface area of a column refers to the total area that is exposed on the exterior of the column. In the context of a column, surface area typically includes both the lateral surface area (the sides of the column) and the base area

Formula for Surface Area of circular column is = Circumference X Height (h)

Formula for circumference of circle is = 2 π r

So, The Formula for Surface Area of circular column is = 2 π r h

Value of π = 3.14

r – Radius of Column, So, r (radius) = Diameter of column  / 2

As per drawing diameter of column = 400 mm

So, r (radius) =400 /2 = 200mm / 0.20 m

h – Height of Column, As per drawing diameter of column = 5.00m

So, the surface area of column is = (2 π r h)

(2 π r h) =2 x 3.14 x 0.20 x 5.00 = 6.28 m²

Total Surface Area / Painting Area / Shuttering area of Column is = 6.28 m²

Volume of Circular column / Concrete volume calculation for circular column

Volume = Area X Height

Area of circle = πr²

So, Volume of circular column = πr² h

So π=3.14, r=0.20 m & h = 5.0m

πr² h = 3.14 x 0.20 ² x 5.0

Volume of Circular column / Concrete quantity of Column is = 0. 628 m³
