Given the radius of the semicircle as r, the task is to find out the Area and Perimeter of that semicircle.
Input: r = 10 Output: Area = 157.00, Perimeter = 31.4 Input: r = 25 Output: Area =981.250000, Perimeter = 78.500000
In mathematics, a semicircle is a one-dimensional locus of points that forms half of a circle. The area of a semicircle is half the area of the circle from which it is made. Any diameter of a circle cuts it into two equal semicircles.
Area of Semi-Circle = 1⁄2 * π *r2
Perimeter of Semi-Circle = π *r
where “r” is the radius of the semicircle.
Below is the implementation of the above approach:
The Area of Semicircle: 157.000000 The Perimeter of Semicircle: 31.400000
