Circumference of a half circle
WebThe area of the semi-circle is equal to half of the area of a circle, whose radii are equal. Therefore, Area = πr 2 /2. Thus, we can define three different formulas to find the perimeter of circle (i.e. circumference of a circle). Formula 1: When the radius of a circle is known. Circumference of a circle = 2πr WebRemember that the perimeter is the distance round the outside. The perimeter of a semicircle is half of the circumference plus the diameter. \ [Circumference\, of\, circle=\pi d=\pi\,\times...
