## How To Find The Arc Length Of A Sector

#### Arc Length and Area of a Sector Sheet 1

You can find both arc length and sector area using formulas. Or you can take a more “common sense” approach using what you know about circumference and area. Let’s look at both of these concepts using the following problems.

Arc length and sector area. We can use our knowledge about the area of a circle to help us find the area of a sector. We know that the area of a circle is given by $$A = \pi {r^2}$$ but if a sector is only a part of a circle, we can just find the area of the part. For example, since a full rotation of a circle is $$2\pi$$ radians, we know that any smaller angle would be a fractional part of

#### Arc Length and Area of a Sector Sheet 1

In order to find the area of an arc sector, we use the formula: A = r 2 ?/2, when ? is measured in radians, and; A = (?/360)?r 2 when ? is measured in degrees. The arc sector traced out by angle A in a circle of radius r is the grey shaded area. The arc sector formula is useful for determining partial areas of a circle. Let us examine a sample problem to see an application of the arc

The Sectors Calculator. Show values to . . . 'arc' and so on, it should, more correctly, be something like 'length of radius' or 'arc-length' etc, and 'angle' means 'angle at the centre'. A problem not dealt with by this calculator is where the length of the chord (c) and the height (h) between the chord and arc are known, and it is required to find the radius (r). r = (c? / 8h) + (h / 2
