The radius of a circle is calculated by measuring the distance from the centre of the circle to any point (In a straight line) of the outside of the circle. (2 or 2 pi r) :)

In Math and Arithmetic

The unit circle is a circle that can be used to find trigonometric functions..
The equation of the unit circle is x^2 + y^2 = 1..
So it is any circle with radius 1.

In Arctic Circle

No. The only line of latitude that is a great circle is the equator. Incidentally, any pair of longitude lines 180 degrees apart from each other would form a great circle.

Answered

In Arctic Circle

No..
Any great circle on the earth has a circumference of about 24,000 miles..
The circumference of the Arctic Circle (and the Antarctic circle too) is about 9,945 miles..
…Imagine circles around the North Pole. The closer to the pole the circle is, the smaller it is. If you were right there at the North Pole, you could walk a 10-foot circle around it. The Arctic Circle is a circle around the pole, but about 1,570 miles south of it..
The only circle around the pole that's a great circle is the Equator. ( Full Answer )

It's line of latitude that makes a circle. with the North Pole as the centerpoint.

A quarter of a circle is 2/8 of a circle. Add to that an eighth (1/8) of a circle (not eight) and this equals 3/8 of a circle. This equates to 37.5 % of a circle.

The pupil is a hole surrounded by the iris which is the colored part of your eye. The pupil gets bigger and smaller because the iris expands or contracts to let more or less l…ight in so you can see better. Have you ever noticed red-eye taken in a photo with flash. Well it is actually the light from the flash bouncing off of the back of your eye, if the pupil was a solid black dot it would not show the reflection coming out ( Full Answer )

There are a few ways that you can. 1. Circumference- the distance around the circle. 2. Diameter- the distance from one midpoint to the opposite midpoint. 3. Radius- The… distance from the center of the circle to any edge. there may be other ways to measure a circle but these are the most used/most important. ( Full Answer )

Find the diameter, then multiply that by Pi (about 3.1416). The result is the circle's circumference.

To get the circumference of a circle first you have to find the diameter of the circle and multiply the diameter by Pi (3.14 in short). so it is the diameter * Pi.
