Of a circle
you multiply the radius by two to find the diameter
then you use the formula for circumference which is: diameter times pi
pi is usually used as 3.14 because the real number goes of forever (3.14159265358979323...)
The person who gave us the value of pi you got that answer off a calculator you DO NOT USE A PI BUTTON ON A CALCULATOR because all calculators have a digit limit and you may get a number that is smaller or larger than that number since Pi is indefinate there is no other way that humans can configure pi without using 3.14 or 22/7 just wanted to say that :)

How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find a circumference of a circle that has a fraction as a radius?
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
What is the circumference when the radius is r?
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
