Remember the circle eq'n.;-
C = 2 pi r
By algebraic rearrangement
r = C / (2*pi)

What is the circumfrence of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
How do you find the radius of a circle if you don't have the area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
How do you find area and circumfrence of a circle?
It depends on what information you have: radius, diameter, lengths of tangents from a point outside the circle, length of chord and its distance from the centre, etc. Also, the term is circumference, not circumfrence.
What are the parts of a circle?
A part of a circle is called an arc. The defined values for a circle are: radius, diameter, chord, area, circumference, and the arcs. There is the circumfrence, semi circle, arc, diameter,chord,segment,radius,quaderent
Finding the circumference of a circle with a radius of 6.3?

Given a circle with a radius of 4 which is the circumfrence?
25.1
What is the formula for the circumference of a circle given a radius?
Circumfrence=diameter X 3.14 (diameter=2 X radius)
How do you find the circumfrence of a circle if you have the radius?
the circumfrence of a circle is pi times it's radius squared.

18.84
What is the circumfrence of a circle with a radius of 11?
22*pi
How do you get the circumfrence for a circle?
Pi times radius squared.
How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
What is the circumfrence of a circle with a radius of 5?
The circumference is about 31.415 units.
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
What is circumfrence and how do you find it?
The circumfrence is like a perimeter. It is the area around a circle. You can find the circumfrence of a circle by using this formula. Pi x R2 or Pi times the radius squared.
What is the radius of a circle with a circumfrence of 8?
8 divided by (2*pi) = a radius of 1.273239545 linear units
What is the circumfrence of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
