The circumference of the large semicircle is pi-r radius of the smaller semi circles are r1 r2 r3 r4... thus their circumference is pi-r1 pi-r2 so on.. pi-r = pi(r1+r2+r3..)
The circumference of a semicircle is pi times the radius plus the diameter.
Oh, dude, so the diameter of a circle is just the distance across the circle passing through the center, right? Well, to find the diameter when you know the circumference, you divide the circumference by π (pi), which is like 3.14 or something. So, for a circle with a circumference of 52 inches, the diameter would be 52 divided by π, which is about 16.5 inches. Easy peasy!
A semicircle has 180 degrees
Circumference of a circle is measure with the formula: C = 2*pi*r where C is the Circumference, and r is the radius. Hence, the circumference of a circle with radius 4 m would be: C = 2*pi*4 = 8*pi Rounded to 2 decimal places, this comes to 25.13 m . Hope this Helps.
