GCSE Secondary Maths Age 13-17 - Shapes & Area: Perimeter and Area - Circles - Explained

The video tutorial explains how to calculate the total cost of building a fence around a semicircle field with a diameter of 50 meters. It covers the calculation of labor costs for three days, finding the perimeter of the semicircle, and determining the cost of the fence. The tutorial emphasizes the importance of not rounding off numbers until the final calculation to avoid errors. The final cost is calculated by adding the labor cost to the fence cost, and the video concludes with an explanation of the marks allocation for the problem.
