6.2 Area

Area, in simple words, is the surface size of a given shape. Again, there are a few formulae you need to learn at the basic level. Harder questions give you multiple shapes combined together to work out part of an area in it.

  • Area of circle: πr2
  • Area of semi-circle: 1/2πr2
  • Area of square: side2
  • Area of rectangle: length × width
  • Area of triangle: 1/2 × base × height
  • Area of cylinder: 2πrh + 2πr2
  • Area of sphere: 4πr2
