A circle is a round shape and oval is a a small and not full round shape

Circle:
A circle is a geometrical shape that is perfectly round and consists of all points in a plane that are equidistant from a fixed center point. It is one of the most basic and important shapes in geometry.

Properties of a Circle:
- Center: The center of a circle is the fixed point inside the circle from which all points on the circumference are equidistant. It is typically represented by the letter 'O'.
- Radius: The radius of a circle is the distance from the center to any point on the circumference. It is denoted by the letter 'r'.
- Diameter: The diameter of a circle is the distance across the circle passing through the center. It is equal to twice the radius (d = 2r).
- Circumference: The circumference of a circle is the distance around its edge or perimeter. It is calculated using the formula C = 2πr, where π (pi) is a mathematical constant approximately equal to 3.14159.
- Area: The area of a circle is the measure of the space enclosed by the circle. It is calculated using the formula A = πr².

Applications of Circles:
Circles have numerous applications in various fields, including:
- Architecture: Circles are often used in architectural designs, such as circular windows or domes.
- Engineering: Circles are used in designing gears, wheels, and pulleys.
- Art: Circles are a common shape in art, used to create patterns, mandalas, and abstract designs.
- Sports: Many sports involve the use of circular objects, such as balls used in soccer, basketball, and tennis.
- Transportation: Circular traffic signs and roundabouts utilize the properties of circles for efficient and safe traffic management.

Oval:
An oval is a geometrical shape that resembles a stretched or elongated circle. It is a closed curve that is symmetrical about its center. Ovals are also referred to as ellipses.

Properties of an Oval:
- Center: Similar to a circle, an oval also has a center point from which all points on the curve are equidistant.
- Major and Minor Axes: An oval has two axes - a major axis (longest distance across the oval) and a minor axis (shortest distance across the oval).
- Eccentricity: The eccentricity of an oval determines its shape. A circle has an eccentricity of 0, while an elongated oval has an eccentricity greater than 0.

Applications of Ovals:
- Art and Design: Ovals are often used in art and design to create visually pleasing and balanced compositions.
- Architecture: Ovals are used in architectural designs to create unique and aesthetically pleasing structures.
- Sports: Some sports fields, such as athletics tracks or swimming pools, have oval shapes to accommodate different events and optimize space usage.

In conclusion, circles and ovals are both important shapes in geometry. While circles are perfectly round and have various applications in different fields, ovals are elongated versions of circles and also find their use in art, design, and architecture.
