This worksheet may help you know about Circular Sector. A Circular Sector is portion of circle enclosed by two radii and an arc. The formula used to calculate the area of the circular Sector is,

**Formula**

Sector Area = (π r2 θ) / 360

Where,

A is the Area of the circular sector.

R is the radius of the circle.

ANGLE is the central angle in radius.

For Example:

calculate the Area of the Circular Sector whose radius is 5 & angle is 300.

Solution:

Substitute the given data in the above formula, we get

A = π x 52 x 30 / 360

= 2356.195 / 360

= 6.545

When it comes to online calculation this Circle Sector Area Calculator is an essential tool to make the calculation easy.
