Semicircle Area
Area of the semicircle is given by half of the area of circle because the semicircle is half of the circle. The formula for the area of the semicircle is:
Area of Semicircle = (Area of Circle)/2
Area of Semicircle = (πr2)/2
where,
- r is the Radius of Semicircle
- π = 22 / 7 or 3.14
Area of Semi-Circle is measured in Square Units.
Finding Area of Semicircle
How to find Area of Semicirlce is explained using the example added below,
Find the area of semicircle with radius 14 cm
Area of Semicircle(A) = (πr2)/2
A = (22/7).(14).(14)/2
A = 308 cm2

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.
