The Waltz Radius Ruler

slide_1

The Waltz Radius Ruler is a ruler or tool developed by Stanley J. Waltz Jr. and can actually change the way we measure circle or round objects.

We are not asking or telling you not to learn the formula mathematically, were just making it a whole lot simpler.

This tool/ruler can be used to get the radius of a curve or an arch without using a formula, a formula that still allows for a margin of error.

What’s so great about the Waltz Radius Ruler?

You will not have to have a background in mathematics; you just pull it out of your pocket or toolbox, and measure the radius in seconds.

If we get this in the Common Core Standards,

it will have a significant impact on the future and employees will become more efficient therefore they will save time and money.
