the distance around a circle
Multiply the diameter by 'pi' .
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
The value of pi is the relationship of a circunference to its diameter. For instance, if you have a circle whose circunference is 9.42477 cm, you shall have a diameter of 3 cm. Any measure of a circunference divided by its diameter shall generates the same numeric value, the pi number.
The formula is:Volume of a circle = 0

If you know the diameter of a circle, multiply that by pi (approximately 3.14). If you know the radius, multiply it by 2 x pi.
If you are referring to the diameter(the distance across the circle or the length of the longest line segment that is passing through the center of the circle), then the answer will be 12 in, since that the diameter is twice the length of the radius. But if you are talking about the circunference, you could use the formula C=2pi(r) or C=pi(d). Thus the answer will be 37.68 in. Please be more specific next time you ask...=)
Pi ( π ) is the ratio of any circle' s circunference to its diameter.It's an endless number, so usually it is rounded to 3.14.So, to calculate a circunference's length, you have to do:(Diameter)x(Pi (consider it as 3.14))=(Perimeter)Here are some more digits of the Pi:3.14159265358979323846Check more about it on the realted links.
what is th hospital formula
The formula is:Volume of a circle = 0
The formula for thorium(IV) oxalate is Th(C2O4)2.
Area formula for circle= --,,- r 2
The perimeter of a circle is called the circumference. Its formula is C = pi x diameter. The value of pi is often rounded to 3.14 for problem solving purposes. So just plug in the values for pi and the diameter into the formula to get the circumference of the circle: 3.14 x 600mm = approximately 1884 mm.
