The purpose of mathematics learning is to understand the basic concept and use it in everyday life. So teaching and learning activities should be centered on the basic concepts. The author use Hawgent dynamic mathematics software to prove the formula for the area of a circle. This research uses...
A circle is, a set of points equal distrance (radius) from a fixed point (center point) on a plane. Now that we have a set definition for a circle, let's quickly define the variables involved in the formulas of a circle. Area of a Circle (variable:A)is the area within the circle...
the area of a circle, however, or even a triangle can be more complicated and involves the use of various formulas. To truly understand the concept of area—and why it's important in business, academics, and everyday life—it's helpful to look at the history of the math concept, as ...
