Circumference of a circle = 2*pi*radius or pi*diameter
It is: 2*pi*radius or pi*diameter
r = 6.8437 cm
circumference = 2*pi*radius or pi*diameter
a circomference
Circumference of a circle = 2*pi*radius or pi*diameter
It is: 2*pi*radius or pi*diameter
r = 6.8437 cm
circumference = 2*pi*radius or pi*diameter
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
a circomference
20 (cm) 8 inches
7*pie=21.99114
circomference of a circle = pi*diameter = pi*14
The radius of a circle is half the circle's diameter
the radius of a circle is r
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
