## Fractional Part Of A Circle Formula

The following formula is used to calculate the fractional part of a circle.

F = (d / 360) * pi * r^2

Variables:

- F is the area of the fractional part of the circle

- d is the degree of the sector

- pi is a constant approximately equal to 3.14159 r is the radius of the circle

To calculate the fractional part of a circle, divide the degree of the sector by 360. Multiply the result by ? and the square of the radius of the circle. The result is the area of the fractional part of the circle.

## What is a Fractional Part Of A Circle?

A fractional part of a circle refers to a portion or segment of the circle that is less than the whole. This is often represented as a fraction of the circle’s total area or circumference. For example, if a circle is divided into four equal parts, each part represents a fractional part of the circle, specifically one-fourth or 0.25 of the total circle. This concept is commonly used in mathematics, particularly in geometry and trigonometry.

## How to Calculate Fractional Part Of A Circle?

The following steps outline how to calculate the Fractional Part Of A Circle.

- First, determine the degree of the sector (d).
- Next, determine the radius of the circle (r).
- Next, gather the formula from above = F = (d / 360) * ? * r^2.
- Finally, calculate the Fractional Part Of A Circle (F).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.
