Hi, today is Monday, again. As promised here is my second article about cute geometric shapes.
Last week we had fun with the bunny who wanted to know the area of a trapezoid. This week our cute bunnies continue helping you with geometry.
The shape what we are going to discuss is a circle. As for me the most important geometry shape. You can ask why. But just imagine a car with 4 square wheels.
A circle may be defined as a set of all points in a plane that are at a given distance from the center. The distance from the center to the edge of the circle is called the radius. The diameter of the circle is a line that starts at one side and ends on the other side of the circle.
Look at the cute picture below. What is the area (S) of that circle?
You can compute the area of circles by using the following formula:
Where:
S — is the area of the circle;
r — is the radius of the circle;
? — is the irrational number 3.141 592 653.
In case you want to know more about our bunny-shaped circles find yourself a good geometry tutor on TutorZ.
