Geometry Formulas List

The following is a collection of different formulae related to geometry that you can use according to the shape of the geometric object.

The perimeter of a Square = 4(Side)
Perimeter of a Rectangle = 2(Length + Breadth)
Area of a Square = Side2
Area of a Rectangle = Length × Breadth
Area of a Triangle = ½ × base × height
Area of a Trapezoid = ½ × (base1 + base2) × height

Basic geometry formulas where the mathematical constant π is used are,

Area of a Circle = A = π×r2
Circumference of a Circle = 2πr
The curved surface area of a Cylinder = 2πrh
Total surface area of a Cylinder = 2πr(r + h)
Volume of a Cylinder = V = πr2h
The curved surface area of a cone = πrl
Total surface area of a cone = πr(r+l) = πr[r+√(h2+r2)]
Volume of a Cone = V = ⅓×πr2h
Surface Area of a Sphere = S = 4πr2
Volume of a Sphere = V = 4/3×πr3


r = Radius;
h = Height. and,
l = Slant height
