'If you measured both circumference and diameter in inches instead of in centimeter would it affect the value of pi?

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!

If you have measured both the circumference and diameter in inches instead of centimetre would it affect the value of pi?
no, pi is a unitless numerical constant
What is the perimeter of a circle which has a diameter of 10 cm?
In the case of a circle, it is common to call this "circumference" instead of "perimeter". Just multiply the diameter by pi.
What is the diameter of a circle whose circumference is 4 inches?
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
What is the circumference of a circle if the diameter is 2.6Cm?
The circumference formula is C=3.14(or pi) times diameter so from there, you plug in. C= 3.14( use pi on your calculator to make it more accurate) times 2.6 so the approximate circumference of that circle is 8.164 if you used 3.14 instead of pi. if you used pi, your answer would be about 8.168
Why do you measure the diameter of the pipe instead of the circumference of the pipe?
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.)
If you measured both circumference and diameter in inches instead of in centimeter would it affect the value of pi?
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.

What is the length of a car park if it is measured using a trundle wheel with circumference of 126 cm and it rotates 77 times?
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.
If you had used the ruler and measured in inches instead of is centimeter would it affects the measurement?
yes , cause inches and centimeters are two different measurements .

Convert diameter to 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.)

What is the circumference of a circle with 3.14 used instead of pi?
That would depend on its diameter or radius which have not been given
What is the formula for finding the radius?
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.
How do find the diameter if there is no given radius?
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.
