circumference = 2 pi r
so 2 x pi x r
don't need diameter
----------------------------------------
Or you could use the diameter only, using this version of the formula
C = pi x d
You'll note that d is 2 x r, so effectively you're just using a rearranged form of the C = 2 x pi x r formula.

How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
What the circumference for ft and using 3.14?
Circumference of a circle = 2*pi*radius or diameter*pi
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
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
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
What is the diameter and radius of the circumference 16.956?
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
What the circumference for ft and using 3.14?
Circumference of a circle = 2*pi*radius or diameter*pi
How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
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
What are the formulas for finding the circumference diameter and radius?
circumference: Pi(3.14) x radius squared Diameter: radius squared radius: diameter divided by 2
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for 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)
