Sectors Arc Length And Area Gcse Maths Revision Guide Tutor In 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. to do this, write down the formula for the arc length, input the numbers you’ve been given and then solve the equation to. Step by step guide: area of a sector. arc length; the arc of a circle is part of the circle’s circumference. its length can be found using the formula \frac{\theta}{360} \times \pi d. for example, in this sector, \theta=30^{o} and the radius is 8 \ cm. this means the diameter is 16 \ cm. the arc length can be found using the formula.

Aob is a sector of a circle with angle 42°, as shown. the area of the sector aob is 28 cm 2. (a) find the radius of the circle, giving your answer correct to 2 decimal places. we know the area and the angle and want to find the radius so we will need to substitute the information into the formula for the area of a sector and solve to find the. Example 1: calculate the arc length (quadrant) calculate the arc length of the sector shown below. give your answer to 3 decimal places. find the length of the radius diameter. the radius of a circle is the length of the line segment from the centre of the circle to the circumference. here the radius = 6cm6cm.

Example 2: sector area & arc length. the sector of a circle has centre c as shown. find the area of the sector and the arc length to 1 decimal place. [2 marks] the angle is 120 \degree, which means that this sector is \frac {120} {360} as a fraction of the whole circle. so, we get: \textcolor {blue} {\text {sector area}} = \dfrac {120} {360. The angle of the sector is 150°. calculate the area of the sector. give your answer correct to 3 significant figures. o cm2 (total for question 1 is 2 marks) 8 cm 8 cm 150° 2 aob is a sector of a circle, centre o and radius 18 cm. the angle of the sector is 125°. calculate the length of the arc ab. give your answer in terms of π. o cm.
