How do you find the area of a square with a semi-circle?
You add the area of the square with the area of the semi circle.
How many cm are there in a semi circle?
First the circle diameter must be given. for example, for a semi circle of diameter 8 centimeters:Step 1: the circumference of the full circle (= pi x Diam). result is: 25.12 cmStep 2: Divide the circumference in half. This is the length of just the curved part of the semi-circle. result: 12.56 cmStep 3: Add the diameter to the result of step 2.Step 4: The result is 12.56 + 8 = 20.56 cm. This is the perimeter of the semi-circle!Note point: There are 360 degrees in a circle, so a quarter of a circle has 90 degrees no matter what size the circle is. Half a circle has 180 degrees.
