This is one simple but really useful tool, that will help you find some of the basic measures of any circle. In fact, the only thing you need to know to solve any circle is its radius / diameter. This would be totally enough, to find anything for such a figure. To do this, you need ot use some standart formulas, which can be found everywhere over the Internet. But the matter of this article is to share with you a circle calculator, so lets get back to this:
Just enter one of the measures in the calculator and press the "Solve" button next to the field to find the other measures. It's a simple tool and you are not supposed to have any big issues with it, if I installed it properly ... This tool is written by a guy named Chris Brown, who allows anyone to freely use his code and place this tool on a site.
