A guide to geometry formulas for computing perimeter, area and volume.

This application is a free guide to geometry formulas for calculating the perimeter, area and volume of geometric shapes and volume bodies.

In the "Perimeter" section you can find formulas for the following figures:

rectangle, square, trapezoid, parallelogram, rhombus, triangle, circle, arc, arc length according to Huygens formula.

In the "Area" section you can find formulas for the following figures:

- flat figures: rectangle, square, trapezoid, parallelogram, regular polygon, rhombus, circle sector, circle, circle segment, ring (in radii and diameters), ring sector;

- triangle: area formula, Heron's formula, area through angles, right triangle, isosceles triangle, equilateral triangle;

- Volumetric bodies: spheres, cube, round cone, cylinder, rectangular parallelepiped, truncated cone, spherical segment, spherical layer, spherical sector;

- regular polygons: triangle, quadrilateral, pentagon, hexagon, polygon;

- Pyramids: a triangular pyramid, a quadrangular pyramid, a hexagonal pyramid, an area across the height;

- the lateral surface of the pyramids: a pyramid, a truncated pyramid, through the height;

- prisms: triangular prism, quadrangular prism, pentagonal prism, hexagonal prism;

- the lateral area of ​​straight prisms: a straight prism, a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism.

In the "Volume" section, the formulas for the following figures are given:

- bodies of rotation: a ball, a cylinder, a cone, a ball segment, a spherical layer, a ball sector,

truncated cone;

- Pyramids: a pyramid, a truncated pyramid, a regular pyramid, a triangular pyramid, a quadrangular pyramid, a pentagonal pyramid, a hexagonal pyramid, a tetrahedron;

- prisms: a cube, a rectangular parallelepiped, a straight prism, a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism.
