In this tutorial, we are going to see the Golang program to find the perimeter of a Circle. Perimeter is the total length of the boundary of any closed figure. Formula Perimeter of Circle - 2 * 22 / 7 * r r - radius of a Circle For example, the radius of a Circle is 10 cm so the perimeter of a Circle is − perimeter = 2 * 22 / 7 * 10 = 62.8571428 Finding the perimeter of a circle within the function Algorithm Step 1 − Declaring the variables for ...

In this tutorial, we are going to see the Golang program to find the Area of a Trapezium. The area is the total space covered by any closed figure. Formula Area of Trapezium - ½ * (b1 + b2) * h b1 - length of one parallel side of a Trapezium b2 - length of another parallel side of a Trapezium h - the distance between the parallel sides of a Trapezium. For example, the length of one parallel side of a Trapezium is 10 cm and the other parallel side is 8 cm, and the distance between ... Read More
