circumference is π*d. In this case it is 8π feet ≈ 8 * 3.1416 ≈ 25.1327 feet■

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 ;)
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
circumference = 2πr = 2π x 6 = 12π units
pi times the diammeter 3.14159 x diameterDan's answer:circumference= pi X diameter.2pi X Radius=Pi X Radius (x2)
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 is 11pi inches
Circumference of the circle: 7.4*pi cm
31x3.1416=circumference
150.8
65.94
Approx. circumference = multiply diameter by 22 and divide the product by 7. Exact circumference = Pi x diameter.
-- Exact circumference = 2pi meters -- Approximate circumference = 6.283 meters
The circumference of any circle when divided by its diameter has the exact value of pi
(circumference=2πr or πd) so the circumference in exact form would be π726.4

They put the value of pi as about 3 but even today we do not know its exact value only that the circumference of a circle divided by its diameter is equal to pi
Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.
