The following operations are all roughly the same thing.
Pick whichever one seems easiest to you.
-- Multiply the circumference by 0.318
-- Divide the circumference by 3.142
-- Divide the circumference by 'pi'. Here is 'pi' to 15 decimal places.
'pi' = 3.141 592 653 589 792
You don't have to use all of them, or even most of them. The more
you use, the more accurate your answer will be. But even if you
only use " 3.14 ", your answer is better than 99.94% correct.
-- Most accurate: Divide the circumference by 'pi' with a calculator.
All of these give you an approximate answer.
Are you asking how to find the exact answer ?
There is no way in mathematics, and you can tell your teachers we said so.
circumference of a circle = pi * diameter.
Diameter = circumference/pi
The diameter of a circle is directly proportionate to the circumference. You can find the diameter of a circle by dividing the circumference by the value of Pi (3.14) OR you can find the circumference by multiplying Pi by the diameter. it is a line that halves a circle
3.14 * Diameter2
circumference of a circle = diameter*pi or 2*pi*radius
Divide the known circumference by pi to find the diameter of the circle.
circumference/pi = diameter
circumference of a circle = pi * diameter.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
Diameter = circumference/pi
The diameter of a circle is directly proportionate to the circumference. You can find the diameter of a circle by dividing the circumference by the value of Pi (3.14) OR you can find the circumference by multiplying Pi by the diameter. it is a line that halves a circle
Multiply the diameter by pi (~3.14) to get the circumference.
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.
