No because pi is a ratio.
Exactly. You could measure it in Pan-Galactic Gargle Blasters and it would still have the same value. JHC!
no, pi is a unitless numerical constant
In the case of a circle, it is common to call this "circumference" instead of "perimeter". Just multiply the diameter by pi.
To find the length of the circumference we would use C = Pi times Diameter, so if we want to find the diameter instead of the circumference we just need to rearrange the formula: D = circumference divided by Pi1. move the diameter over the = sign and divide by the circumferenceSo for your example:D = C divided PiD = 4 divided by Pi ( if you can't use a calculator use 3.14)D = 1.27323....D = 1.3 to one decimal placehope this helped
Oh, dude, you just gotta take the diameter and multiply it by π (pi) to get the circumference. So, if the diameter is 2.6 cm, the circumference would be 2.6 x π, which is around 8.17 cm. Easy peasy, right? Like, who even uses circles in real life anyway?
You could, but if you do, you will have to divide the circumference by π, and that's an irrational number. And, think of placing the pipe in a rectangular box with two sides the same length as the diameter of the pipe. It fits, and it makes the question much, much simpler. (Doesn't it? Sorry if my answer's too long.)
No. "pi" is the 'ratio' of circumference to diameter of a circle. It doesn't care what the unit is,just as long as both are measured in the same unit.

7 7 x 126 cm = 9,702 cm = 97.02 metersThis could have been a much more interesting problem if you had giventhe diameter of the wheel instead of its circumference.

The circumference of a circle is a little more than 3 times the diameter, so for a rough, approximate conversion, multiply the diameter by 3. For a better conversion, multiply the diameter by π instead. π is a the Greek letter whose name sounds like 'pie'. It is often written 'pi' instead of π. π cannot be written down absolutely accurately, but you can make your conversion more and more accurate by using more and more accurate values for π. Here are some values for π in order of increasing accuracy, 3.1 3.14 3.142 3.1416 3.14159 3.141593 (This list can go on forever.)

The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
the question makes no sense? 3 yards doesnt have a circumfernce. Only Circles have circumfernes ( the perimeter of a circle ) BUT..in case you want a cirlce of radius 3 yards, then it's circumference is 6Pi, and if instead you diameter is 3, than it is 3Pi.
In that case, you must use what is given.For example, if the circumference is given, then the diameter is [ C / pi ] .If, instead, the area is given, then the diameter is [ 2 sqrt( A / pi ] .In any problem-solving situation, fretting about what you don't havedoesn't get you anywhere. Just relax, and use what you dohave.
2 meter circumference rotating 1 revolution per second produces a linear speedof 2 meters per second.The question can be slightly more exciting if you give the diameter of the wheel,or even its radius, instead of its circumference.
