Circumference = Pi * diameter
Divide the known circumference by pi to find the diameter of the circle.
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
To Find Diameter:Multiply circumference by 0.3183, ordivide circumference by 3.1416Other things to do with circles:To find Circumference:Multiply diameter by 3.1416, ordivide diameter by 0.3183To Find Radius:Divide diameter by 2, ormultiply circumference by 0.15915, ordivide circumference by 6.28318
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
Circumference = Pi * diameter
circumference/pi = diameter
Divide the known circumference by pi to find the diameter of the circle.
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
Multiply the diameter by pi (~3.14) to get the circumference.
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
circumference of a circle = pi * diameter.
you multiply the diameter 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?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
Divide the circumference by pi (pi = 3.14159 or rounded to 3.14 for rough approximation) to find the diameter of a circle.
