Yes if the diameter is rational. But it need not be if the diameter is irrational.

If the diameter is 3/pi units, for example, then the circumference will be (3/pi)*pi = 3 units.

Is the circumference of a circle considered to be a whole number?

No because the circumference of a circle is pi times diameter and pi is an irrational number


The diameter of a circle can be divided into the circumference how many times?

The diameter of a circle can be divided into the circumference of a circle pi times. The number pi is about 3.14 in decimal form. Because pi is an irrational number, it cannot be written as a fraction of integers or as a terminal or repeating decimal. The circumference of a circle is said to be pi times the diameter, so by dividing the diameter into the circumference, we would get pi as a quotient.


Is the circumference of a circle to the diameter constant?

The Circumference (C) of a circle will ALWAYS be 3.1415926 times its Diameter (D). This irrational number (which goes on forever) is called "pi". C = pi x D This will work for any circle, because as the circle gets bigger or smaller, so does the circumference by the same scale.


What is the circumference of the circle which radius is 3.5cm?

Circumference of circle: 2*pi*3.5 = 22cm rounded to the nearest whole number


What is the exact radius of a circle with the circumference of thrity six meters?

My understanding is that as the measurement of the circumference of a circle is derived from an equation using "pi" with pi being an indefinite number, the measurement of the circumference of a circle is also an indefinite number, but the figure can be rounded back to a predetermined number of decimal places.
