Gcse Sectors Of Circles And Arc Lengths Youtube Gcse; edexcel; circles, sectors and arcs edexcel arc length. the circumference of a circle is its outside edge, and is the same distance from the centre at every point along its length. For example, the radius of a circle is 4cm.4cm. the area of the circle is π × 4 2 = 16π cm2 = 50.265…cm2π × 42 = 16π cm2 = 50.265… cm2. step by step guide: area and circumference of a circle. circumference of a circle (πd) (π d) (πd) the circumference of a circle can be found by multiplying the diameter by π.π.
Circles Sectors And Arcs Gcse Maths Steps Examples 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 distance from the centre of a circle to its circumference. the plural of radius is radii. separate the area of a circle into two sectors the major sector and the minor sector. to calculate. A sector is an area of a circle enclosed by two radii (radiuses) and an arc. a sector looks like a slice of a circular pizza. the curved edge of a sector is the arc. two radii in a circle will create two sectors. the smaller sector is known as the minor sector. the bigger sector is known as the major sector. 1. sector, centre o.radius of the c. angle of the sector is 150°.8 c. 150°o 8 cmcalculate the area of the sector.gi. ures. cm2(total for question 1 is 2 marks)2aob is. sector of a circle, centre o and. cm. the angle of the sector is 12. °.a18 cmcalculate the length. e your answer in terms of π.o 125° 18 cmb3se.

A = (θ 360) * π * r². where: θ is the angle (in degrees) of the sector. r is the radius of the circle. for example 2, if the radius is 8 cm and the angle is 90 degrees, the sector area would be: a = (90 360) * π * 8² ≈ 50.27 cm². these formulas are instrumental in solving various problems including those found in the gcse maths steps.
