Math Antics - Circles, Circumference And Area - YouTube.
Circles appear everywhere in maths. Mathematicians just can’t get enough of them. Here, we’re going to introduce a few of the terms used to describe parts of a circle, and then we’re going to look at calculating the area and perimeter of a circle. So, the terms we’ll need are shown on the diagram and described in further detail below.
Calculating the circumference of a circle. The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from.
Q. The homeowners association wants to enclose a circular playground in a fence. The need to find the amount of fencing they need to purchase. Will they need the area or circumference of the playground?
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. This diagram shows the circumference of a circle. There are two other.
