Perimeter of a Quarter Circle

The perimeter (P) of a quarter circle consists of:

  • The arc length of the quarter circle.
  • The two radii that form the straight sides.

As quarter circle is one fourth of a circle, thus its arc length is also one fourth of circumference of circle.

Thus, arc length of quarter circle = 2πr/4 = πr/2

Perimeter of quarter circle = πr/2 + 2r

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.
