Radius of a Semicircle Calculation
Semicircle is half the circle. The circles radius is simply half the diameter of the circle. Therefore, the radius of the semicircle is equal to the radius of the circle.
This tutorial gives you the semicircle radius formula and explains how to calculate the radius of the semicircle given the circumference or the diameter.
Radius of a Semicircle,
r = Diameter (d) / 2
r = Circumference / Pi
Pi is a constant = 3.14
Let us learn how to find the radius of the semicircle using the below tutorials.
