ArcCalc is a simple and easy to use app for calculating all the parts of a circular arc or segment. Given any two values, this app will calculate for the radius, length, width, height, apothem, angle, and area of a circular arc. Very useful for carpenters, architects, handymen, machinists, welders, designers, technicians, engineers, do it yourselfers, and many more. This calculator utilizes simple and complex mathematics to do all the calculating for you. If you are one of those who went to calculus class and wondered where all that knowledge can be practically applied -- this is one of them. Features: * This calculator will do calculations for all twenty one cases when given any two inputs of the radius, length, width, height, apothem, angle, and area of a circular arc. All possible solutions are presented for the given two inputs. * Length units in feet, inch, meter, centimeter, millimeter can be specified for all inputs and values to be calculated. Angle unit can be in degrees or radians. * All calculations are automatically saved in the "Saved Results" window. Saved results are grouped by date of entry. Just swipe to delete an entry no longer needed. * Complete error checking function for inputs that are out of range in relation to the other given input. The calculator will give the limits for all inputs that are out of range. * Results can be shared by email. The Arc Calculator is the mobile app version of the popular online calculator "The Complete Circular Arc Calculator". Please check it out at https://www.handymath.com/cgi-bin/arc18.cgi?submit=Entry. Please check out also other calculators you might need at www.handymath.com and on the App Store. Additional Notes: The circular segment screenshots above gives a visual illustration of the parts of a circular segment. "Width" is used in place of the more proper term "Chord" as more people go with "Width".

Feature The ShapeInfo is useful application for calculating shape lengths, angles and area. You can get some calculated values, lengths and angles of the shape, from choosing and entering values in the text boxes. How to use 1. Choosing shape from the list. 2. Enter the value to the box upon the orange points. You can change the formation of the orange points by "NEXT" button (orange color) or tapping orange/gray point near the box that you are going to enter the value. 3. You can get calculated values of the shape, immediately after entering values. Applications - For the software developer, the mechanical engineer, the dynamics engineer and the surveying engineer. - Study mathematics for high school students. Functions - Calculate lengths, angles and the area for the right triangle, the triangle, the sector, the circle and ellipse. - Calculate volume for the triangular pyramid, the triangular prism, the circular cone, circular cylinder and the sphere. Shapes - Right triangle - Triangle - Sector - Circle - Ellipse - Triangular pyramid - Triangular prism - Circular cone - Circular cylinder - Oblique cutting circular cylinder - Sphere Disclaimer Appsys does not accept responsibility for any loss, which may arise from reliance on the software or materials published on this site.
