GCSE Secondary Maths Age 13-17 - Geometry & Measures: Circumference of a Circle - Explained

The video tutorial explains how to calculate the length of an arc in a circle sector. It begins by identifying the given data, including the radius and angle of the sector. The tutorial then demonstrates how to calculate the circumference of the entire circle using the formula πD. Next, it shows how to find the arc length by using the given angle and proportion of the circle's circumference. The result is rounded to three significant figures, and the tutorial concludes with an explanation of the marks awarded for the problem.
