To find the perimeter of a semi circle, you have to know the diameter (the length of its straight edge). For example, if the diameter of your semi circle is 12 centimeters, the formula becomes P = 1/2 (3.14 × 12) + 12.


What is the perimeter of a semi-circle with a diameter of 8cm? Step 1: Find the circumference of the full circle. Step 2: Divide the circumference in half. This is the length of just the curvy part of the semi-circle. Step 3: Add the diameter. 12.56 + 8 = 20.56 cm. This is the perimeter of the semi-circle!


A semicircle is one half of a circle. It looks like a straight line with a circular arc connecting its ends to one another. The straight edge of the semicircle is the diameter and the arc is half the circumference of a full circle with the same diameter.


Perimeter of a Semicircle The perimeter of any shape is the total length of all its sides. Since a circle has no sides, its perimeter (also known as its circumference ) is the length of the circle ...

The perimeter of a semicircle is 1/2 of the circumference of the corresponding complete circle plus the diameter of the circle. The distance around the outside of a semicircle is generally called its perimeter. A semicircle can be seen as the shape that is formed when a circle is cut in half along its diameter.

The perimeter of a semicircle is not half the perimeter of a circle*. From the figure above, you can see that the perimeter is the curved part, which is half the circle, plus the diameter line across the bottom. Recall that the perimeter of a circle is 2πR, (See Perimeter of a circle).
