Example: If a circle has a diameter of 10 units, its circumference would be C = 10 × 3.14 = 31.4 units. 2. Using the Circle’s Radius. Suppose you know only the radius of a circle – half the length of ...

Since technology is not going anywhere and does more good than harm, adapting is the best course of action. That is where The Tech Edvocate comes in. We plan to cover the PreK-12 and Higher Education ...

You have shown that the circumference of a circle is π × diameter. Image caption, TIP: Try it with any circular object. Whatever the size, the circumference is always just over 3 × diameter.

Namely, a circle is the set of all points (that’s the curve you drew with your pencil) that are all the same distance from some common point (that’s the spot where you pinned the string down ...

When you divided the y coordinate (circumference) by the x coordinate (diameter), you should have found something close to the value of pi, one of the most important mathematical constants. Pi, which ...

There is a trick to measure the area of a circle. In fact, this was a trick people used in the past to find the area under a curve on a graph (before technology gave us better methods).

Every year, the celebration of Pi Day (March 14 is 3.14) grows more ambitious. Math teachers love to dream up unique classroom activities to celebrate Pi for it endless opportunity to calculate (3 ...
