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 π r = π 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 π (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 π r, then the circumference of the semicircle is 1/2 (2πr) + d = (π r + d) units.

 

Semi-Circle Column = (π 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 = (π 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 π r and D = 2r.

Given the diameter,

Perimeter of a column formula = π 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 = π 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 π r and D = 2r.

Given the radius,

Perimeter of a column formula = 2 πr

 

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 πr

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 = 2πr.

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)/ 2π.

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
