radius = pi/(2*pi) = 1/2 or 0.5
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius or diameter*pi
The circumference of a circle is 2*pi*radius or pi*diameter
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius or diameter*pi
Radius of a circle = circumference/2*pi
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
Circumference of a circle = 2*pi*radius or pi*diameter
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
