circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
The letter or character used to represent the ratio of the circumference to the diameter of a circle is the Greek lower case letter π, called "pi."
Divide the circumference by Pi (3.14159), and that will give you the diameter. Divide that number by 2 to find the radius.
Circumfernce = 2*pi*r So 2*pi*r = 60*pi r = 30 units of length.
A circle with a 4-foot diameter has a circumference of about 12.57 feet.
40.8407045
R is the symbol
Multiply the diameter by pi, and the answer will be the circumference.
circumference = 84*pi
Circumference of a circle = 2*pi*radius or pi*diameter
Circumference of a circle = 2*pi*radius or pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
Divide the circumference by pi (~3.14) to get the diameter.
π is the circumference of a circle by the length of that circle's diameter. usually its circumfernce is 3.14159 to its diameter of 1 in that approximate ratio.

Neither radis nor rafius are recognised words in the English mathematical language. I suggest you check and amend your spellings and resubmit the question.
A radius squared fits pi times into a circle (The area of a circle divided by pi is the radius squared).
