Geometry semicircle
Webannie, to find the perimeter of a semicircle on top of a triangle, you have to know 3 things: 1) The word "semicircle" literally means "half of a circle". 2) The formula for calculating the perimeter of a circle (Which is pi*d, where d is going to be the diameter of the circle --- or in our case the semicircle, and pi means the number π -- or ... WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr.
