– π (pi) is a mathematical constant, approximately equal to 3.14159 If we know the circumference of a circle, we can easily find out its radius by rearranging this formula and solving for ‘r’: r = C / ...

Math and geometry play an influential role in our lives, whether we realize it or not. One such example is measuring circumference using the diameter of a circle. The concept is not only useful for ...

When working with circles it is important to recognise and be able to name different parts of the circle. A segment of a circle is an area enclosed by a chord and an arc. What is the name given to a ...
