This version 1.1 is working with iOS4. A radius calculation calculator. This math application will help anyone, including students, teachers, engineers, architects, carpenters, cabinet makers, and the list goes on. Anyone that works with circles, circular work or needs to find the radius of a part of a circle. Additionally, the program will compute the circumference of a circle, the arc segment length of a circle, the area of the arc segment , and will even provide the central angle of the arc segment. Designed to be easy to use in the construction industry. To find the radius of something like a wall built with a curve or arc it is very important to know what the radius of the wall is if you need to build something that will fit against the wall. Many of todays methods of fabrication require the use of CAD software for design as well as robotic machinery to cut materials, therefore the need of accurate measurements are critical. I have used this radius formula since 1995, and I rely on it!!

RadiusCalc "the results spot on every time"

Chirpychippy - ★★★★★

by Well impressed joiner - Version 1.1 - 03 July 2010

Purpose made joiners who make anything with with a radius involved should get this. Saves so much time on the calculator having to input time consuming "intersecting chords formula" and I've found the results spot on every time. Reported incompatibility with IOS 4 with the developer and 1 week later the app is back working. Genuine developers like this is what the app store needs more of. Five stars for both the app and the customer service from me.
