The circumference of a circle (the distance around the perimeter) is calculated by mulitplying a constant value called Pi (which equals 3.14 and is true for all circles), times the circle's diameter (distance across the center).
Therefore, to answer your question, C = Pi x D, or 3.14 x 20in, or 62.8 inches.

What is the converse of If two circles have the same diameter then they have the same circumference?
The converse of the statement "If two circles have the same diameter, then they have the same circumference" is "If two circles have the same circumference, then they have the same diameter." This means that if you know two circles share identical circumferences, you can conclude that their diameters are also equal.
What is the answer to circles and circumference?
circumference = 2*pi*radius or pi*diameter
What is the circles diameter if the circumference is 62.8?
diameter = circumference divided by pi = 62.8/3.14 = 20
If circle circumference is 12 what is diameter?
The diameter of a circle with a circumference of 12 is: about 3.82To to this calculation for other circles, just divide the circumference by Pi (about 3.1416). The result is the diameter.
What is the circumference of a centermeter circle?
The relationship of a circles circumference to it's diameter is Pi x diameter. So a 1cm diameter circle will have a circumference of 3.142 cm to the third d.p.
What is the ratio to any circles circumference to the diameter?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
What is the answer to circles and circumference?
circumference = 2*pi*radius or pi*diameter
What is the circles diameter if the circumference is 12.56?
diameter = 12.56/pi
What is the circles diameter if the circumference is 62.8?
diameter = circumference divided by pi = 62.8/3.14 = 20

What is the circumference of a centermeter circle?
The relationship of a circles circumference to it's diameter is Pi x diameter. So a 1cm diameter circle will have a circumference of 3.142 cm to the third d.p.
How do you calculate circumference?
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
Do two circles have the same circumference if they have the same diameter?
Yes.
Do two circles have the same diameter if they have the same circumference?
Yes.
What is the circles diameter if the circumference is 31.4?
It is: diameter = 31.4/pi which is about 10 units
How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
If a circle has a circumference of 6 ft what is the diameter?
If a circle has a circumference of 6 ft, the diameter is: about 1.91 feet. You can easily do this calculation for other circles by dividing the circumference by Pi (about 3.1416). The result is the diameter.
