Area of a Quarter Circle
What is a quarter circle?
A quarter circle is a geometric shape that forms when an arc joins the ends of two radii, creating a right angle at the center of a circle. It has an arc as its curved side and two radii as its straight sides.
How is the area of a quarter circle calculated?
The area of a quarter circle is calculated using the formula: Area = (πr2) / 4, where ‘r’ is the radius of the quarter circle.
What are the properties of a quarter circle?
- A quarter circle has several properties:
- It forms a 90-degree center angle.
- Its area is half that of a complete circle.
- It has an arc-formed curving border.
- It has two right-angled intersecting radii.
- It exhibits order 4 rotational symmetry.
- It finds applications in engineering, architectural design, and geometric computations.
Where is the concept of quarter circles applied?
Quarter circles are applied in various fields including engineering, architectural design, and geometric calculations involving circles and sectors.
What are some examples of calculating the area of quarter circles?
Examples include determining the area of quarter circle flower beds, murals, portions of pool bottoms, or specialty pizzas, given their respective radii or diameters.
Area of a Quarter Circle
A quarter circle is one-fourth of a full circle. It resembles a slice of pie, that is divided into four equal parts. It includes a 90° angle and a curved edge, forming a right-angled sector. Calculating the area of a quarter circle is simple and useful in various applications. This article will guide you through the steps to determine the area, making it easy to understand and apply.
