Semicircle Perimeter
Perimeter of semicircle refers to the sum of the circumference of the semicircle and the diameter of the semicircle. The formula for the perimeter of semicircle is given by:
Psemicircle = Circumference of semicircle + Diameter of semicircle
Psemicircle = πr + d
Psemicircle = πr + 2r, where [d = 2r]
Perimeter of Semicircle = (πr + 2r)
where,
- r is Radius of Semicircle
- π = 22 / 7 or 3.14
Perimeter of Semi-Circle is measured in units such as m, cm, etc.

Finding Perimeter of Semicircle
How to find Perimeter of Semicirlce is explained using the example added below,
Find the perimeter of semicircle with radius 14 cm
Perimeter of Semicircle (P) = (π + 2)r
P = (22/7 + 2).14
P = 72 cm

Semicircle
Semicircle: In mathematics, particularly in geometry, a semicircle is defined as a one-dimensional set of points that make up half of a circle. It is a circular arc spanning 180 degrees, which is equivalent to π radians, or half of a full rotation. Semicircle is a half circle formed by cutting the circle into two halves. It is a circular arc that measures 180°, or π radians, or a half-turn. It only has one line of symmetry, called reflection symmetry.
In this article, we will discuss the concept of a semicircle, including its shape, formula, examples, perimeter, and area.
