How do you figure the diameter of a circle from its circumference?

The circumference = pi x r2, and the diameter = 2r.
So if you start with the circumference, you divide that number by pi (3.1416), then take the square root. What's left is the value of the circle's radius; double it to get the diameter.

How do you figure out the circumference of a circle?
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
If the diameter of the circle is 69mm then what is the circumference of this circle?
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
How do you figure out diameter?
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
What is the circumference of a circle if the diameter is 12cm?
The circumference of a circle if the diameter is 12cm is 37.7cm
What is the circumference of a circle with an diameter of 6cm?
The circumference of a circle with a diameter of 6cm is about 18.85cm
How do you figure diameter of circle using circumference?
Divide the circumference by pi, and that will give you the diameter.
How do you figure out the circumference of a circle?
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
How do you figure out circumference and radius?
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
How do you find the diameter of the circumference if a circle?
There is no such thing as "the diameter of the circumference" of a circle. A circle has a diameter, and a circle has a circumference. If you know one, you can always figure out the other one, because they're very tightly connected. Circumference = (diameter) times (pi) Diameter = (circumference) divided by (pi) "pi" = about 3.1415926536 (rounded). You can use 3.14 and your answers will be very close.
If the diameter of the circle is 69mm then what is the circumference of this circle?
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
How do you figure out the circumference of a circle with 8 meters diameter?
You multiply the diameter by Pi (about 3.1416). The result is the circumference:8m x 3.1416 = 25.1328 meters circumference
How do you figure out diameter?
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
If the diameter of a circle is 80 what is the circumference?
Diameter of a circle = circumference/pi
What is the diameter of a circle if the circumference is 80 -?
Diameter of a circle = circumference/pi
How do you figure permiter of a circle?
