GCSE Secondary Maths Age 13-17 - Geometry & Measures: 3D Shapes - Surface Area - Explained

The video tutorial explains how to calculate the total surface area of a solid shape composed of a cylinder and a hemisphere. The teacher guides through the process of finding the radius using the given surface area of the hemisphere, then calculates the surface areas of the cylinder's base and curved part. The final step involves adding these areas to find the total surface area, with emphasis on expressing the answer in terms of π. The tutorial also outlines the marking scheme for the problem.
