Why would you need to find the circumference of a circle?
As for example when constructing a round-about on a road you'll need to know its perimeter which is the circumference of a circle.
What is a situation where you would need to know the circumference of a circle?
The circumference of a circle would be needed as for example when constructing a circular swimming pool.
How do you find the diameter of a circle if you dont know the circumfrince?
you do not need to know the circumference to find the diameter. You just need to measure one side of the circle to the other .
If you know the circumference what is the radius?
Circumference is calculated by 2pr So if you know the circumference, divide by 2, and then divide by p That answer will be the radius
How do you find circumference of concentric circles?
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
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 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
You have the circumference and you need to know the diameter?
The formula for finding circumference is 2∏r (or ∏d). So to find the diameter, you would divide the circumference by pi (3.14, approximately).
What is a situation where you would need to know the circumference of a circle?
The circumference of a circle would be needed as for example when constructing a circular swimming pool.
How do you find the diameter of a circle if you dont know the circumfrince?
you do not need to know the circumference to find the diameter. You just need to measure one side of the circle to the other .
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
If you know the circumference what is the radius?
Circumference is calculated by 2pr So if you know the circumference, divide by 2, and then divide by p That answer will be the radius
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Why would someone need to calculate the circumference of the circle?
To know how fay you travel in one rotation of the wheel.
How do you find circumference of concentric circles?
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
Can the cumference of a circle be found?
Yes. you need to know the diameter or radius of the circle and then the formula is:- Circumference = Pi*Diameter or Circumference = 2Pi*Radius. An approximate value for Pi is 3.14159.
