What is radius of circle with a circumference of 31 feet?
Circumference of a circle = (pi) x DiameterDiameter = 2 x radiusCircumference = (pi) x (2 x radius)(2 x radius) = Circumference/piRadius = Circumference/(2 x pi) ==> Over to you.
The ratio of the circumference of a circle to its diameter?
The ratio of the circumference of a circle to its diameter is know as PI. PI = 3.14159* = 22/7* This basically means that the circumference of a circle is a little over 3 times the length of the diameter. *Note that PI has an infinite amount of digits following it.
What is the circumference of a circle if diameter is 65mm?
pi*65 which is just over 204 mm
What is approximately equal to 3.1415?
Well, this is the constant Pi. Pi is equal to the ratio of any circle's circumference to its diameter. In simpler terms: Take any sized circle (go on, draw one on paper) and measure how long a piece of string it takes to wrap it once around the circle. This is the circumference of the circle. Now measure the longest distance you can measure in the circle, so that would be from one side to the other side of the circle, over the middle bit, and that value is the diameter. Now take a calculator and divide the circumference by the diameter and voila, you should see a number equal to 3.1415 Go to wiki: http://en.wikipedia.org/wiki/Pi
How can you solve the circumference of a circle if pi has been used as a fraction?
You can either 1)You can divide out the fraction used for pi then multiply by the diameter or 2)Put the diameter over 1 then multiply across with the fraction used for pi.
