How to Calculate Radius of a Semicircle Given Circumference?

Semicircle Radius using Circumference Calculation

Semicircle is half of a circle. When a circle is divided into two equal halves, it forms two semicircles.Let us learn here how to calculate the radius of the semicircle given the circumference.
Formula Used:
Radius of Semicircle
r = Circumference / Pi
Where,
Pi is a constant = 3.14

Let us consider an example to find radius of a semicircle whose circumference is 6cm.
Radius of a Semicircle r = Circumference / Pi
r = 6 / 3.14
r = 1.91
