circumference = pi*diameter
the radius of a cirle is what percent of the diameter
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.
Multiply the diameter by 'pi' .
Yes.

Approximately 37.68 inches. The formula is the value of Pi times the diameter of the cirle. Pi rounds to 3.14. Thus 12 X 3.14 = 37.68.
5.9723 inch
The radius of a circle is always PRECISELY one half its diameter.
The cicumference of any circle divided by its diameter is aways equal to pi.
16 pi = almost exactly 50¼
The radius of a circle is half of its diameter. Since the diameter of the circle is 24 inches, the radius would be 24 inches divided by 2, which equals 12 inches. Therefore, the radius of a 24-inch circle is 12 inches.
circumference of a circle = 2*pi*radius or pi*diameter
