Real- Life Applications
Let us take a look at some of the Real- Life Applications where Circles are being used:
- Real- Life Application One
- This Picture shows a Ferris- Wheel.
- A ferris wheel is basically shaped like a wheel.
- Since most of these amusement rides are fairly large, the outer circle is not made from one piece of steel but rather several little arcs.
- The number of arcs is determines by the number of cars on the wheel.
Question:
- How long would the arc be between the cars if there were 12 cars on a 30-meter tall ferris wheel?
- Real- Life Application Two
- This is a Basketball Court Orientation.
- This is a Diagram of a 4- foot diameter centre court.

Question:
- How long would the arc be between the cars if there were 12 cars on a 30-meter tall ferris wheel?
- Real- Life Application Two
- This is a Basketball Court Orientation.
- There are three 12- foot circles in a Basketball Court:
- One lies at the center of the court and the other two circles lie at each of the free throw lines.
- Here is a diagram.
Question:
- How much paint would be needed to paint all of the areas shown in green colour if one gallon could only covers 130 square feets?

In this Blog.. You will learn about the 4 Properties of Circles.
~ Chords of a Circle ~The Perpendicular bisector of a Chord of a Circle passes through the Centre of the Circle
Equal Chords of a Circle are Equildistant from the Centre of the Centre
The Perpendicular from the centre of a Circle to a Chord bisects the Chord
~ Angles in a Circle ~The angle subtended by an arc at the centre of a Circle is twice the angle subtended by the same arc at the Circumference
An angle in a Semicircle is a Right- angle
The angles in the same segment of a Circle are equal
~ Angles in the Opposite Segments ~The sum of the angles in the Opposite Segments of a Circle is 180 degree
~ Tangents to a Circle ~A tangent of a Circle is perepndicular to the Radius of the Circle drawn from the point of Contact
