**Area and Perimeter of Sectors TC**

The Perimeter is a constant and so we can represent it as twice the radius plus the fraction of the circumference. The area of the sector in the fraction notation can be formed as either a function of r or a function of k, depending on a subsitution of r or k from the perimeter equation.... Hi Erica, The circumference (perimeter) of a circle is given by. circumference = 2 π r. where r is the radius and π is approximately 3.1426. You have a radius of r units so you can find the circumference.

**Find the perimeter of a sector of a circle whose radius is**

2/11/2008 · perimeter of a sector of a circle is twice the radius added to the length of the arc between the two radii, that is 2*R + (the angle in degrees/360 * 2 pi …...In order to calculate the length of an arc or the area of a sector, you must calculate the value of the angle which is made by the arc or sector at the centre of a circle. For example, if the angle is a right angle (90°), then the arc in question is a quarter of the circumference of a circle and that sector area is a quarter of the area of the circle.

## How To Find The Perimeter Of A Sector

### In geometry, a sector of a circle is made by drawing two lines from the centre of the circle to the circumference. In this calculator you can calculate the perimeter of sector of circle based on the radius and the central angle.

- A red carpet 12m long and 1.5m wide is kept for welcoming foreign dignitaries and heads of state .A 10cm wide border runs parallel to the lengths on b
- A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.
- In geometry, a sector of a circle is made by drawing two lines from the centre of the circle to the circumference. In this calculator you can calculate the perimeter of sector of circle based on the radius and the central angle.
- 16/05/2009 · You need to work out the fraction of the area/perimeter which is contained in the sector. This is, handily, the ratio of the angle at the centre of the sector to the full angle (360 degrees).
