GCSE Lesson 2 - Length, Area and Volume

In this lesson we shall cover

  • Circle Vocabulary
  • Area of a Sector
  • Arc Length
  • Volume of a Pyramid
  • Volume of a Cone
  • Surface Area of a Pyramid
  • Curved Surface Area of Cone
  • Volume and Surface Area of a sphere
  • Volume and Surface Area of a Hemisphere

Circle Vocabulary

Some key definitions you need to know about circles

Area of a Sector

Here we deduce the formula for the area of a sector

Arc Length

Here we deduce a formula for the arc length and perimeter

Volume of a Pyramid

We find the volume of different types of pyramids

Volume of a Cone

We deduce the formula for the volume of a cone and do a few examples

Surface Area of a Pyramid

We work out the surface area of triangular based and square based pyramids

Curved Surface Area of Cone

We work out the curved surface area of a cone and the total surface area of the cone

Volume and Surface Area of a sphere

How to find the volume and surface area of a Sphere

Volume and Surface Area of a Hemisphere

Here we work out the volume and surface area of a Hemisphere
