circumference of a circle = pi * diameter.

Divide the known circumference by pi to find the diameter of the circle.

To find the diameter of a circle divide its circumference by pi

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?

circumference=pie x diameter diameter= circumference/pie pie= 3.141592654

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.

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
