Here, we will see program to find area of semi circle in go. Given below, you can find algorithm and program.
Algorithm:
- You are given radius of circle.
- Calculate the area of semi circle using standard formula
- Return this result
Area of a Circle Formula:
area_of_a_circle = (pi * radius * radius) / 2
Input :
a = 3
Output :
14.137167
Input :
a = 5
Output :
39.26991
Code:
package main
import (
"fmt"
"math"
)
func area_of_circle(radius int) float32 {
res := (math.Pi * float32(radius) * float32(radius)) / 2
return res
}
func main() {
area := area_of_circle(3)
fmt.Println(area)
area = area_of_circle(5)
fmt.Println(area)
}
Output:
14.137167
39.26991
