Maths Formulae

  1. Area of a triangle = 0.5 x base x height 

  2. Area of a rectangle = base x height

  3. Area of a parallelogram = base x perpendicular height 

  4. Area of a circle = pi x radius^2

  5. Area of a trapezium = A = 0.5( a + b)h

  6. Circumference of a circle = pi x diameter 

  7. Volume of a cuboid = length x width x height

  8. Volume of a cone = 1/3 x pi x radius^2 x height 

  9. Volume of a prism = area of corss section x length

  10. Sine rule = a/SinA = b/SinB = c/SinC

  11. Cosine rule = a^2 = b^2 + c^2 - 2bcCosA

  12. Area of any triangle = 0.5abSinC
