What are Semicircle Formulas? Examples

The circumference of a semicircle is not equal to half of the circle circumference - you need to add also the diameter of the semicircle, as another boundary was created: P s e m i c i r c l e = P c i r c l e 2 + 2 ⋅ r

Equation of Semicircle

The equation of a semicircle with midpoint (,) on the diameter between its endpoints and which is entirely concave from below is y = y 0 + r 2 − ( x − x 0 ) 2 . {\displaystyle y=y_{0}+{\sqrt {r^{2}-(x

Semicircles, Interiors, and Exteriors of Circles

Since the circumference is C = πR, where C is the circumference, and R is the radius, we can determine the formula for the perimeter of a semicircle which is: The perimeter of a Semicircle = (πR + 2R) units, or after factoring the R, the
