How I do calculate the circumference of a circle?
Formule based= using radius
circumference = 2𝛑r
Using diameter=
Diameter: The diameter is the length of the line through the center that touches two points on the edge of the circle.
Radius: The Radius is the distance from the center outwards.
The Circumference is the distance once around the circle.
Radius = 26000mm
Diameter = 520000
PI = 22/7 or 3.141
To convert the radius from cm to M I am going to divide it by 100
26000/100 = 260 m
Cir 2 x PI x 260
=1633.62817987
