Sector area in radians
WebThe sector of a circle has centre C C as shown. Find the area of the sector and the arc length to 1 1 decimal place. [2 marks] The angle is 120 \degree 120°, which means that this sector is \frac {120} {360} 360120 as a fraction of the whole circle. So, we get: WebArea of a Sector. When the angle at the centre of a circle is given as θ radians, we can define the area of a sector to be 1 2 r 2 θ, where r is the radius. This also follows from the …
