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
