Calculates the section flexure depth with pipe bender or bending machine to obtain given parameters.
Area of an irregular quadrangle with the given sides
Calculates an area of an irregular quadrangle with the given sides
Regular polygon, number of sides and length of side from incircle and circumcircle radii
This online calculator finds number of sides and length of side of regular polygon given the radii of incircle and circumcircle
Side of regular polygon from polygon area
Calculates the side length of regular polygon given the area of the regular polygon and number of sides
Cone development
Calculator of right circular cone / truncated right circular cone development
Rectangle area calculation by perimeter
Rectangle area calculation with known perimeter and aspect ratio
The Rectangle Area Calculator with Perimeter Condition
The Rectangle Area Calculator with Perimeter Condition is a helpful tool designed for solving math problems that involve calculating the area of a rectangle under specific perimeter conditions.
Cylindrical Tank Volume Calculator
Use this calculator to determine your cylindrical tank volume in cubic inches and gallons even if one or both ends are rounded. Especially useful if you've cut the tank in length. If you've got a flat end just leave it blank or enter 0.
Calculation of the edge cut margin to obtain an octagonal face
This online calculator calculates the indentation of the beginning of the cut along the edge of a square in cross-section bar to obtain a regular octagon at the base (the end is a regular octagon).
Construction Volume Calculator
The Construction Volume Calculator allows you to calculate the total volume of a construction project by specifying the volume of various prisms (or rectangular cuboids) and subtracting any volumes you wish to exclude.
Rectangle Area Calculator
The calculator is a useful tool for calculating the total area of a set of rectangles.
Level of liquid in the cylindrical tank, AKA Quarter-Tank Problem
This online calculator finds the height above the bottom of a horizontal cylinder (such as a cylindrical gas tank) to which the it must be filled for it to be full at specified percentage (for example, one quarter full amounts)
Area of a quadrilateral
This article lists several calculators to compute the area of a quadrilateral
Unfolding a 3D sphere to 2D shapes
If you want to made a DIY sphere, you need to unfold the sphere to 2D shapes, or, more strictly speaking, approximate the sphere using petals, or "orange peels" (also called the lunes) on the plane. The calculator calculates basic parameters of such 2D peel and displays coordinates of points for drawing one peel on a plane.
How many circles of radius r fit in a bigger circle of radius R
This calculator estimates how many circles of radius r can be placed inside another circle of radius R.
The area of a convex polygon from the coordinates of the vertices on the plane
This online calculator calculates the area of a convex polygon from the coordinates of the vertices. A convex polygon is built from the vertices using the Jarvis March Algorithm (or Gift Wrapping Algorithm)
Function Plotter
The calculator plots entered functions on the single coordinate plane.
Circular segment - complete solution
The calculator solves arc length, area, angle, height, chord or radius of circular segment by two given parameters.
Volume of the hemisphere cut at an angle
Volume of hemisphere asymmetrically cut by a flat plane under a given angle.
Volume of liquid in a tilted tank with hemispherical heads
Calculates volume of liquid in an inclined cylindrical tank with hemispherical ends.
