Portion of the area of a circle is called a sector.
to find the area of a semi circle measure the length of the straight edge, divide by 2, square it and multiply by pi. This will give you the area of the circle. To get the area of the semi-circle divide your answer by 2
Rewrite the above program so that the program accepts any value for the radius then recalculate the area of the circle.
Radius of circle: 37.68/2pi = 5.996958256 units Area of circle: pi*5.996958256^2 = 112.9826266935 or about 113 square units
Exactly as in the question and a segment of a circle is the area enclosed by a chord and an arc of a circle.
From the north pole to the arctic circle. The area above the arctic circle. There is only one arctic area, but there is also an antarctic area, around the south pole.
The region north of the Arctic Circle is known as the Arctic.

The area north of the Arctic Circle is about 20,000,000 km2 (7,700,000 sq mi) and covers 4% of the Earth.
The region between 66.5 degrees north latitude and the North Pole is called the Arctic Circle. This area experiences the phenomenon of the Midnight Sun during the summer solstice, where the sun remains visible 24 hours a day.
No, the Hudson Bay area is just outside the Arctic Circle.
Part of Alaska lies above the Arctic Circle.
The Arctic
The area north of the Arctic Circle is about 20,000,000 km2 (7,700,000 sq mi) and covers 4% of the Earth.
"High" latitudes. The equator has a latitude of zero. The area between the Tropic of Cancer (at 23.5 degrees north) and the Tropic of Capricorn (at 23.5 degrees south) are the "tropics" or low latitudes. The "polar regions" are above the Arctic Circle or below the Antarctic Circle, where the latitudes are higher than 66.5 degrees (north or south) are "high". The areas between the tropics and the arctic/antarctic are called "mid-latitudes or "temperate zones".
