The portion of a circle which is enclosed within the two radii and the adjoining arc length is the sector of a circle. The amount of space enclosed within the boundary of a sector is known as the area of a sector. The center of a circle is the origin of a sector. Generally, a sector is divided between two sectors. They are minor and major sectors. Arc Length is the distance along the circumference of a circle.

Firstly, note down all the information given. Such as length, radius, and so on.
Then, use an appropriate formula to get a result.
Here is an example to solve a question on arcs and sectors. Let’s look at the given example to understand more about the arcs and sectors of a circle.
Area of a Sector = (θ/360º) × πr2
Arc Length = θ × r, where θ is in radian.
Q. Find the length of an arc cut off by a central angle of 5 radians in a circle with a radius of 8 inches.
Step 1: Note the Radius
Radius = 8 inches.
Step 2: Use the arc length formula
θ × r, where θ is in radian.
Arc length = 8 * 5 = 40 inches.
Why Should you use an arc and sector worksheet for your students?
Using these worksheets will help your students to easily calculate questions on arc length and sector.
