Radius of circle with Circumference - Circle - Mensuration problem solver

What is the radius of a circle when it's circumference is 254 units?

Radius of circle with Circumference

circumference = 254
r =  C / ( 2 * PI )
radius = 254 / ( 2 * PI )
radius = 40.4091
So the radius is 40.4091

Circle :

Circle is a perfect round shape.

Circle Formulas :

A =  PI * r * r

C =  2 * PI * r

d =  r * 2

r =  C / ( 2 * PI )


where,

d = diameter
A = area
C = circumference
r = radius
