What is 270 degrees of a circle as a fraction?
It is: 270/360 or 3/4 in its simplest form
How would your find the fraction of a circle that an arc covers SHOW FULL ANSWER?
There are 360 degrees around a circle and if an arc covers 45 degrees of the circle then the fraction is 45/360 or 1/8 in its simplest form
What angle is form by a semi circle?
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
The mesures of an exterior angle and the adjacent interior angle sum to 360 degrees because they form a linear pair?
No. 360 degrees is a full circle. These two angles, when added together would form a straight line, or 180 degrees.
Three radii in a circle form three angles-Two of the angles measure 130 degrees each-What is the measure of the third angle?
The idea is that three lines coming out from the center point of a circle (three radii) form three angles -- imagine, for an easy example, the Mercedes-Benz logo. Then the question is: if two of the angles each measure 130 degrees, what does the third angle measure? Well, the first two together measure 260 degrees. So, how many degrees in a circle overall are left, once 260 are taken out? There are 360 degrees in a circle, so the answer is 100.
Which meridians paired with their opposite meridians are great circles?
The prime meridian (0° longitude) and the 180° meridian are opposite meridians that form a great circle on Earth. Similarly, the equator (0° latitude) and the 90° latitude (either north or south) also form a great circle.
Are meridians halves of small circle?
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
Does 90 degree west and 90 degree east form a great circle?
No. You have to cross 360 degrees of meridian for a great circle, so 180 degrees East plus 180 degrees West around the equator will form a great circle.
What is located at 20 degrees west and 160 degrees east of the meridians?
The imaginary boundary between the Southern and Northern hemispheres is located at 20 degrees west and 160 degrees east of the Meridians. They are two semi-circular lines that are opposite of each other on the globe, which form an imaginary circle around the earth going through the poles.
What three facts about meridian?
1) They are also called Lines of Longitude 2) They measure the distances in degrees east or west of the prime meridian 3) They run from the North Pole to the South Pole Two antipodal meridians form a great circle including both poles.
What does each pair of meridians make?
Each pair of meridians form a continuous loop around the Earth and meet at the poles. The Prime Meridian and the International Date Line are the two most common pairs of meridians used for navigation and timekeeping.
What is the 0 line of the longitude called?
The zero degrees longitude line is called the Prime Meridian. When the Prime Meridian is combined with the meridian of 180 degrees longitude, the two meridians together form a circle that divides the Earth into the Eastern and Western Hemispheres.
What is the connection between the 0 degrees longitude and the 180 degrees longitude?
Together, they combine to form a single "great circle" around the earth. The circle passes through the north pole, the suburbs of London, the south pole, and the middle of the Pacific Ocean.
What are three facts about meridians?
Meridians are energy pathways in traditional Chinese medicine through which qi flows. There are 12 main meridians that correspond to different organs in the body. Acupuncture and acupressure are techniques used to stimulate points on the meridians to promote health and balance in the body.
Is arctic circle a great 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.
Is the equator the only meridian that is a great circle?
No, besides the equator, any meridian (a line of longitude) can also be considered a great circle. A great circle is defined as the largest circle that can be drawn on a sphere, and any meridian fulfills this criteria.
What is 270 degrees of a circle as a fraction?
It is: 270/360 or 3/4 in its simplest form
