**How To Calculate the Radius of a column Using
Perimeter of Column Formula? | How to calculate of perimeter or circumference
of the column?**

**The
term for the perimeter of a column is called the circumference of the column.**

The
circumference of a column formula is used to find the circumference (Perimeter)
of a column. The circumference of a column is the length of its boundary or the
entire arc of the circumference of a column. So, the circumference of a column talks
about the circumference of a column, hence it is also called the circumference
of a column formula. In this article, we will learn about the perimeter of the column
formula with solved examples.

**Perimeter
or circumference of Column Formula**

**The perimeter of a column** = 2 Ï€ r = Ï€ D units

Therefore,

r
= radius of the column

D
= diameter of the column.

**Examples
on Perimeter of Column Formula**

**Note: **d is the
diameter, R is the radius and a constant with the value Ï€ (3.14 or 22/7).

** **

**What
Is the Perimeter of Column Formula for a Semi-circle Column?**

** **

**Semi-Column
means half of the full Column**

As the circumference of the circle is 2 Ï€ r, then the circumference of the semicircle is 1/2 (2Ï€r) + d = (Ï€ r + d) units.

**Semi-Circle
Column = (Ï€ r + d)**

Example: The radius of a column is 0.6m. Using the perimeter
of a Semi circle column formula, calculate the circumference of the column.

** **

**Solution:**

**To find: Perimeter of the Semi-circle column**

Given:

Radius (r) = 0.6m

Diameter = 2r = 2x0.6 = 1.2m

The perimeter of circle formula = (Ï€ r + d)

C = (3.14x0.6 + 1.2) -= 3.084m

The circumference of a Semi-circle is 3.08m

**What Is the Perimeter of column Formula
When Diameter Is known?**

As we know that the perimeter of the column formula
= 2 Ï€ r and D = 2r.

Given the diameter,

**Perimeter
of a column formula = Ï€ d**

** **

Example: The diameter of a column is 1.2m. Using the
perimeter of a column formula, calculate the circumference of the column.

**Solution:**

**To find: Perimeter of column with
diameter**

Given:

Diameter = 1.2m

The perimeter of circle formula = Ï€ d

C = (3.14 x1.2) -= 3.768m

The circumference of a column is 3.768

**What Is the Perimeter of column Formula
When radius Is known?**

As we know that the perimeter of the column formula
= 2 Ï€ r and D = 2r.

Given the radius,

**Perimeter
of a column formula = 2 Ï€r**

** **

Example: The radius of a column is 0.6m. Using the perimeter
of a column formula, calculate the circumference of the column.

**Solution:**

**To find: Perimeter of the column with the diameter**

Given:

Radius (r) = 0.6m

The perimeter of circle formula = 2 Ï€r

C = (2 x 3.14 x 0.6) = 3.768m

The circumference of a column is 3.768

** **

**How To Calculate the Radius of a column Using
Perimeter of Column Formula?**

Circumference of column formula = 2Ï€r.

As we know the value of the circumference or
perimeter of a column, we can calculate the radius by deriving the value into
the formula.

Therefore,

**R
= (circumference of column)/ 2Ï€.**

**Solution:**

**To find: Radius of column with Perimeter
of column**

Given:

Perimeter of circle formula = 3.768 m

The perimeter of circle formula = 3.768/ (2x3.14) = 0.6m

The Radius of a column is = 0.6m
