Step 2: Calculate the Diameter, which is 2 multiplied by the radius i.e 2r. Now, when you know the etymology, you won't forget what a semicircle is: just remind yourself how the semifinals are connected with the finals, and you'll know how to link a semicircle to a circle. Step 2: Once, the equation is obtained, solve for "r". Since the perimeter has already been given, we can find the radius of the circle the same way. Every formula is used in certain context. That's right, it's parameters is just five times four. It is based on these definitions will the perimeter of the semi-circle be found. Adding the two components, we get P = r + 2r. Every formula is used in certain context. However, the perimeter of a semicircle has a different formula since a semicircle is the half of a circle, and it consists of a curved and a straight boundary. Since the circumference is \(C = R\), where \(C\) is the circumference, and \(R\) is the radius, we can define the formula for the perimeter of a semicircle which is: The perimeter of a semicircle \(=\color{blue}{(R + 2R)}\)units, or after factoring the \(R\),the perimeter of a semicircle \(=\color{blue}{R( + 2)}\), Find the circumference of a semicircle with a diameter of \(10\) units. As such, it is twice the radius, and it is why it is denoted as; Below are the steps to calculate the perimeter of a circle, Step 1: write out the formula computation, Step 2: Calculate the Diameter, which is 2 multiplied by the radius i.e 2r, Step 3: Compute the Perimeter of the circle. If the diameter of a semicircle is given, the circumference can be calculated with the help of the formula: Circumference = (d/2) + d, where 'd' is the diameter of the semicircle and is equal to 22/7. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge.
