Calculate Circle Sector Area

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
