Circumference is (2)(pi)(radius) or (diameter)(pi).
The exact size is mathematically an infinitely long number because Pi is an irrational number and you are attempting to multiply by it. Obviously it must have an exact size but it cannot be shown mathematically. You can calculate it to any desired measure of accuracy, down to less than the width of an electron if you wish. But it is still not exact.

The exact circumference of a circle with a radius of 6 is?
circumference = 2πr = 2π x 6 = 12π units
What is circumference of a circle with a radius of 4 cm?
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 ;)
Exact circumference of a circle 24cm?
If you're talking about the radius being 24 cm, then the the circumference is exactly 48 PI. If the diameter is 24 cm, then the circumference is 24 PI
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.
What is the circumference of a circle with 56 cm?
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.

How do you find the circumfernece of a circle?
If you want an approximate answer, you can measure it with string. If you want an exact answer and know the radius, multiply by 2*pi to find the circumference.

Circumference of the circle: 7.4*pi cm
What is the circumference of a circle with 56 cm?
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.
Is the distance around a circle called the radius?
No, the distance around a circle is called the circumference. The radius is the distance from the exact center of the circle to the edge of the circle and is one half of the diameter. The diameter is one straight line passing through the center of the circle from one end to the other. The circumference can be determined from the following equation: C = pi * d or C = 2*pi*r
