Then it multiplies stride length times the number of steps to calculate how far you walked. Archimedes used a similar method to estimate the circumference of a circle, and so to estimate pi.

How to Solve for Radius in Excel. The radius of a circle or a sphere is the distance between the center and the edge. The radius can be used to calculate a circle's diameter, area and circumference.

Yes, this is essentially the same equation used to find the circumference of a circle if θ is measured in radians (which it should be).

It asks you to find the circumference of a circle. In order to do so you first have to find the circle's diameter through the use of an isosceles triangle.
