The circle theorems include:
- The angle at the center is twice the angle that's at the circumference.
- The angle in a semicircle is a right angle.
- Angles in the same segment are equal.
- The opposite angles in a cyclic quadrilateral equal 180°.
<h3>How to explain the theorem?</h3>
It should be noted that circle theorems are simply about finding the arc lengths, angles, and areas of the sector of the circle.
Some of the theorems include the angle at the center is twice the angle that's at the circumference, the angle in a semicircle is a right angle, etc.
The circle theorem can be used in real life application by a photographer to focus his lens. The radius of the lens will be used to determine the focal length. Also, it should be noted that the aperture of the camera depends on the diameter of the lens.

Answer:
In economics a demand is defined as the quantity of goods and services that customers are capable to buy and that they find desirable to buy at a particular price for that period of time .
Demand is dependent on the customer's needs and wants each customer may have different things that they consider to be needs to them and those they consider as just wants.
This also depends on affordability, if one doesn't have the money to buy the product then the demand isn't effective.
When the price of the product rises usually it's demand decreases and vice versa when the price fall the quantity of that product demanded will increase.
Answer:
Display Rule
Explanation:
According to my research on studies conducted by various sociologists, I can say that based on the information provided within the question this difference is due to a formation of the Display Rule. This term refers to informal cultural norms that individuals learn very early in their lives from different interactions within the society that they are part of. Which is why each culture is different, such as is exhibited by the emoticons used.
