The area (land and sea) enclosed by the Arctic Circle is known as the North Polar Region.
North Polar Region
== == Inscribed is a polygon inside a circle with all points on a given point in the circle. Circumscribed is a circle inside a polygon with any given point touching just one point on the polygon. Hope this helped.
The center of the largest circle that you could draw inside a given triangle is going to be at the incenter of the triangle. This is the point where bisectors from each angle of the triangle meet.
The incentre, which is the point at which the angle bisectors meet.
Global distances - KY to the arctic circThe state of Kentucky (USA) is located between 36°30'N and 39°9'N. The arctic circle is on 66°33'N. Given the fact that there is 10,000 km from the north pole to the equator (a distance spanning 90°), there must be between 3,043 km and 3,338 km from Kentucky to the arctic circle.It's about 2,000 miles (3200 km) from central Kentucky to the Arctic Circle.
We've not been given a circle.
That's a "circle". The given distance is the circle's radius, and the given point is the circle's center.
The Arctic Circle is the parallel of latitude that runs 66° 33' 44" North of the Equator, and the Antarctic Circle is the parallel of latitude that runs 66° 33' 44" South of the Equator.66 1/2 N and 66 1/2 SThe latitude of the Arctic Circle is set at 66 degrees, 33 minutes, 44 seconds north of the equator. The Antarctic Circle is set at 66 degrees, 33 minutes, 44 seconds south of the equator.
... touches each circle in exactly one point on each circle. given any two circles where none is entirely inside or inside and tangent to the other, there are at most four straight lines that are tangent to both circles.
A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.Yes, it does.
This is the definition of the area of a circle. The formula to find area is given as pi times the radius raised to the second power, where pi is approximated as 3.14.
semi circle
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
