**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 m^{2}**Total Surface Area / Painting Area / Shuttering area of Column is = 6.28 m ^{2}**

**Volume of Circular column / Concrete volume calculation for circular column **

Volume = Area X Height

Area of circle = πr^{2}

So, Volume of circular column = πr^{2 }h

So π=3.14, r=0.20 m & h = 5.0m

πr^{2 }h = 3.14 x 0.20 ^{2 }x 5.0

**Volume of Circular column / Concrete quantity of Column is = 0. 628 m ^{3}**

Keep on working, great job!
