C = pi*d
By algebraic rearrangement
d = C /pi
NB pi is a mathematical constant with the value of 3.141592654....
For school work it is approximated to 3.14.

How do you calculate the diameter of 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
If you know the circumference of a circle which steps can you follow to find its diameter?
Diameter = circumference/pi
What formula do you use if you know the diameter of a circle and want to find the circumference?
circumference of a circle = pi * diameter.
How do you fimd the radius and diameter of a circle?
If you know the circumference, use the formula for circumference (C=pi*diameter), but rearrange it to get Diameter= circumference/pi. Then just sub in values.
How do you find the circumference of Neptune if you know the diameter?
you multiply the diameter by pi.
How can i find circumference if you know diameter?
Circumference = Pi * diameter
What is circumference if you know diameter?
The circumference is the diameter x 2.
How do you find circumference if you know diameter?
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. :)
How do you find the diameter of a circle when you know the circumference?
circumference/pi = diameter
What is the diameter of a circle with a inch circumference?
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.
How do you get a circumference and diameter with pi?
Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiRR is the radius.so 2R is twice the radius (a.k.a. The Diameter)That leaves you withCircumference=Diameter*PiThe circumference can be found by multiplying the diameter by pi, and the diameter can be found by dividing the circumference by pi.

How do you find the diameter of a circle in the terms of 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
How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
If you know the diameter of a circle how could you find the circumference?
Multiply the diameter by pi (~3.14) to get the circumference.
If you know the circumference of a circle how do you get the diameter?
Divide the circumference by pi.
