- A sector is a part of a circle that is shaped like a piece of pizza or pie. To find the area of this piece, you need to know the radius, arc length and the degree of the central angle. With this information, finding the area of a sector is a simple matter of plugging the numbers into given formulas
- For each sector you need to work out both the arc length and the area of the sector. For the next question you are given the angle at the centre, 98 degrees, and the arc length, 10cm. You need to find the radius, marked x
- Area of Sector with respect to Length of the Arc If the length of the arc of the sector is given instead of the angle of the sector, there is a different way to calculate the area of the sector.

- e the length of an arc and the area of a sector. Lesson Notes This lesson explores the following geometric definitions

It's much easier to think of a sector as the shape of a slice of a circular pizza (or cake, or pie, or ) and an arc as the curvy bit at the end of it (where the crust is) If the angle of the slice is θ (that's the Greek letter theta) then the formulas for the area of a sector and the length of an arc are just fractions of the area. Solution for For the given sector area, find the the arc length: 10ft F E Area = 130.83 ft2 O 24.31 ft O 26.17 ft O 31.59 ft O 39.92 f In this following video, the formulae for area of sector = (1/2)r²Ө and area of triangle = (1/2)absinӨ (in this question both a and b are the radii of the circle so the area of triangle can also be seen as (1/2)r²sinӨ) are used. Note that all angles are calculated in radians in this question. Make sure the calculator is set in radians mode too when doing calculations For any theta, the length of the arc is given by the formula (if you work in radians, which you should: The area of the sector is given by the formula (theta r^2)/2 Why is this? If you remember, the formula for the perimeter of a circle is 2pir. In radians, a full circle is 2pi. So if the angle theta = 2pi, than the length of the arc (perimeter) = 2pir Arc length and sector area are only sufficient if the arc length is provided in an angular measurement (radians, degrees or the equivalent). If the arc length is provided in a distance measurement (cm, furlongs) then you can't determine whether yo..
