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!

The perimeter of this semicircle is 41.12 inches. Now let's find the perimeter of the other semicircle that had the diameter of 10 feet. In this case, we're given the diameter.
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.

To find the area of a semicircle, start by finding the area of the full circle using the formula πr^2, where r is the radius of the circle. If you don't know the radius, you can find it by dividing the diameter of the circle by 2. Once you've found the area of the full circle, just divide it by 2 to find the area of the semicircle.
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.
