About this app

Solve your geometric calculations with precision and speed thanks to ArpEvol.

ArpEvol is a comprehensive tool designed to facilitate the study and resolution of mathematical problems. Whether you are a student, teacher, or a professional requiring exact calculations of geometric figures and solids, our application offers you a fast, reliable solution that works entirely offline.

What can you calculate with ArpEvol?
Our calculator is divided into three main modules, covering a wide range of geometric needs:

📐 Areas Module: Obtain the surface area of 20 flat figures and solids, including:
• Triangle, Square, Rectangle, and Circle.
• Parallelogram, Trapezoid, Rhombus, and Rhomboid.
• Pentagon, Hexagon, and Regular Polygons of n sides.
• Curved figures: Annulus, Circular Sector, and Ellipse.
• Surface areas of solids: Cylinder, Cone, Cube, Tetrahedron, Frustum of a Pyramid, and Frustum of a Cone.

📏 Perimeters Module: Calculate the boundary length of 16 essential figures:
• Basic figures: Triangle, Square, Rectangle, and Circle.
• Polygons: Trapezoid, Parallelogram, Rhombus, Rhomboid, Pentagon, Hexagon, Heptagon, and Octagon.
• Specialties: Regular Polygon, Annulus, Circular Sector, and Ellipse.

📦 Volumes Module: Determine the capacity of 26 different geometric solids:
• Prisms and Polyhedra: Cube, Cuboid, Rhombohedron, Parallelepiped, and Prisms (Regular/Irregular Triangular, Pentagonal, Hexagonal, and of n sides).
• Pyramids: Square, Rectangular, Pentagonal, and Frustum of a Pyramid.
• Round Solids: Cylinder, Hollow Cylinder (Pipe), Cone, Frustum of a Cone, Sphere, Spherical Cap, Ellipsoid, and Torus.
• Platonic Solids: Tetrahedron, Octahedron, Dodecahedron, and Icosahedron.

Key Features:
• Visual Guide: Each calculation includes a reference image to help you correctly identify the necessary variables (such as radius, edge, height, or apothem).
• Offline Use: Do not depend on an internet signal; perform all your calculations anytime and anywhere.
• Efficient Interface: Designed to avoid distractions, allowing you to focus on your tasks and get instant results.
• Educational Tool: Ideal for middle school, high school, and technical-level students looking to verify their exercises or streamline their geometry studies.

Optimize your time and improve your mathematical workflow. ArpEvol puts a complete library of geometric solutions in your hand so that complex calculations are no longer an obstacle.
