The process you would use to find the circumference of a circle completely
depends on what information you already have about the circle. For example,
you might be given the circle's area, or its radius, or its diameter, or the length
of one radian of arc along the circumference, and each of those would require a
different method to find the circumference.
The easiest example is the one where you know the circle's diameter. In that
case, simply multiply the diameter by (pi) to get the circumference.
The next easiest case is the one where you have the circle's radius ... let's say
the radius is 1.5 meters. Knowing that the radius is half of the diameter, you
first double the radius, and find that the diameter 3.0 meters. Then you get
the circumference just as you did in the first example ... multiply the diameter
by (pi). With a radius of 1.5 meter, you would find that the circumference is
about 9.425 meters. (rounded)

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.
How do you find the relationship between the circumference and diameter of a circle?
Circumfrence = pi * diameter It can be experimentally derived very easily.
How do you find the circumfrence of a circle if you have the diameter?
By multiplying the diameter by pi, since the circumference of a circle is 3.14 times the diameter.
How do you find the circunference of a bowl?
You get a string that can fit around the bowl and wrap the string around it and mark where they overlap. measure the string and there is the circumfrence!
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 to find circumfrence?
Multiply pi by the diameter.
How do you find the diameter of a circle if you have the circumfrence?
divide by pi which is 3.1415927 and on and on
HOW TO FIND the circumfrence of a circle?
The circumference of a circle is (diameter) multiplied by (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.
How do you find the diameter if you have the circumfrence?
i have tried searching that too but it was unfound i hope yu find your answeeer!
How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
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.
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.
How can pi be used?
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
How would you find the circumfrence of a circle?
If you know the diameter of the circle, multiply that by Pi (about 3.1416). The result is the circumference.
How do you get the circumfrence of a circle?
divide
How do you find the relationship between the circumference and diameter of a circle?
Circumfrence = pi * diameter It can be experimentally derived very easily.
