How do you calculate the diameter or radius of each circle?
Using the Circumference And Area.
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
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
How do you find the circuferance of a circle in a square?
If the circle touches each edge of the square then its diameter is the same as the side of the square and its circumference is pi times the diameter.
What is the are of a circle with 4 mm?
You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility gives you a different area.

What is the area of a circle with 4mm?
You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility leads to a different area.
What are three different size circle?
Each circle with a different radius (or diameter or circumference) is a different size circle.
What do 159 and 3.14 have to do with each other?
The circumference of a circle with diameter 50.61 is about 159
How do you find the circuferance of a circle in a square?
If the circle touches each edge of the square then its diameter is the same as the side of the square and its circumference is pi times the diameter.
What does the diameter tell us about the circle?
It tells us how wide the circle is through its centre to each side of its circumference.
How do you find the degrees of a circle?
1. Multiply pi (3.14) by the radius of the circle (half of the diameter which is the length of the circle on the widest part).2. Square your result.This uses the formula:Area=πr2where π=3.14
How do you find circumfrence?
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.

What is the are of a circle with 4 mm?
You neglected to say whether the 4mm is the radius of the circle, or the diameter,or the circumference. Each possibility gives you a different area.
What is the diameter of a 9.9ft circle?
That depends on what exactly the "9.9 ft" is.Is it the radius of the circle ?Is it the circumference ?Each of those choices produces a different diameter, and you'veneglected to specify that information in your question.
