Best Answer

The circumference equals pi times the diameter .

C = pi . d

pi = 22/7 = 3.14

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

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.

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. :)
