We've not been given a circle.
That depends on the questions which have not been given but in general circular measurements are:- Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
That depends on its diamter which has not been given but the circumference of a circle is diameter times pi
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
People have been drawing circles for a very long time.
That will depend on the circumference of the circle which has not been given
That would depend on its diameter or radius which have not been given
Not enough information, since you don't specify ANY information about the circle.For example, if you know the diameter, the circumference is pi x diameter; if you know the radius, the circumference is 2 x pi x radius.
This question has already been answered in detail and the answer is 38.83251825 or 39 inches to the nearest foot.
Take the dark green fraction pieces and place them on the red circle. When all the pieces have been placed correctly you will see that the green pieces cover the red exactly.
The circumference of a circle is NOT 360 degrees. The circumference is the distance around the curve of the circle. This has a measurement unit of length, not degrees. The angular displacement, in going completely around any point is 360 degrees and that follows from the definition of a degree.
The circumference of a circle divided by its diameter is equal to pi and it's unique because there is no other number that has been discovered that is equivalent to its value.
