The circumference of a circle (C) is the diameter (D) times pi (approximately 3.14 or 22/7). So, the equation would be: C=D*3.14. For example, if the diameter was 4', the circumference would be 12.56'.
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
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
The circumference of a circle can be found by multiplying pi ( π = 3.14159 ) by the diameter of the circle. If you know the radius, the diameter is twice as large.
The diameter times Pi gives you the circumference.
circumference/pi = 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. 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.

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?
Divide the known circumference by pi to find the diameter of the circle.
circumference of a circle = pi * diameter.
Divide the circumference by pi.
The answer depends on what information you are given. If you know the circumference, then divide by Pi and that is the diameter. Half of the diameter is the radius. If you don't know anything about the circle, you would need to measure and find the diameter.
Diameter = circumference/pi
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
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. :)
The circumference is equal to the diameter multiplied by pi. Therefore, if you know the circumference, you can divide by pi to get the diameter.
