What does circumference come from?

Answer 1

-- Collect all the information you know about the object whose circumference

you need to find, such as its radius or diameter.

-- Substitute the information you have into a mathematical formula that relates

circumference to the information you have.

Answer 2

This all begins with a story of mathematicians who were arguing about the division of the circle. At first, one said we should split circles in percentiles, whilst another said in quartiles. These were rejected. What happened was that one decided to measure the radius of a circle, for example it was 6 units. So, he started to measure the perimeter of the circle (circumference) and marked a segment whenever the value of the radius was found. after measuring the entire circle, he noticed that there were 6 segments, and a part of a segment. So he tried again with different radii and there were always 6 segments and a bit. So, this 6 and a bit was divided by 2, to yield "3 and a bit" which is what we call pi. So, as you've noticed, the formula for circumference is: the radius multiplied by 2 times pi, which is the correct formula! An alternative way would be to find the value of the constant that the radius is multiplied by to get the circumference as they are directly proportional, so a constant must exist, which you will find to be 2 x pi.

Answer 3

To get the CIRCUMFERENCE you multiply the diameter times pi. (Which is 3. 14)

Answer 4

The term "circumference" comes from Latin roots "circum" (around) and "ferre" (to carry). It refers to the distance around the outer boundary of a circle or any curved geometric figure.
