That's called a "great circle" of the sphere.
-- It's any circle whose center is at the center of the sphere.
-- Its diameter is equal to the diameter of the sphere.
-- Its area is equal to 1/4 the surface area of the sphere.
-- The shortest distance between any two points on the sphere is
along the piece of the great circle on which they lie. (There's only
one, unless the two points are the opposite ends of a diameter.)
What else can I help you with?
Are all parallels great circles?
No, not all parallels are great circles. A great circle is the largest possible circle that can be drawn on a sphere, and it divides the sphere into two equal hemispheres. Parallels, or lines of latitude, are circles that run parallel to the equator, and only the equator itself is a great circle. Other parallels, such as those near the poles, are smaller circles and do not divide the sphere into equal halves.
What is the ratio of the area of a circle to the area of a square drawn around that circle?
The ratio is pi/4.
4 circles are drawn inside a big circle of radius 10 cm in such a way that there is no overlaping and all 4 are equal in size what is the radius of the largest circle that you can draw in the middle?
The radius of the largest circle you can fit is 2.72cm
What degrees of two meridians which can form a great circle?
Two meridians can form a great circle when they are 180 degrees apart, as they represent opposite points on the Earth's surface. For example, the Prime Meridian at 0 degrees and the Antimeridian at 180 degrees are such meridians. Any two meridians that are 180 degrees apart will create a great circle, which is the largest circle that can be drawn on the surface of a sphere.
What is circumscribed area and inscribed area of regular polygon?
circumscribed means the polygon is drawn around a circle, and inscribed means the polygon is drawn inside the circle. See related links below for polygon circumscribed about a circle and polygon inscribed in a circle.
What circle is the largest circle that can be drawn around a sphere such as a globe?
general astronomy
How to draw great circles and small circles drawn?
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
What is a great cicle?
Much bigger and better than a regular circle... But seriously, a great circle on a sphere is a circle that runs along the surface of that sphere and cuts it into two equal halves. It is the largest circle that can be drawn on a given sphere. The center of any great circle is the center of the sphere.
A half circle of 180 degrees of arc which connects the earth's poles is known as?
The half circle of 180 degrees of arc connecting the Earth's poles is known as a great circle. This is the largest circle that can be drawn on a sphere and it divides the sphere into two equal hemispheres.
Can there be a straight circle?
Circle in 2D is a straight figure drawn on a plane. But if we take it as a sphere,it cannot be straight.
What is the difference between spherical and circle?
A sphere is a three dimentional shape, a circle is a two dimentional shape. You can't pick up a circle, it can only be drawn. In differential geometry, a one dimensional sphere is a point, a two dimensional sphere is a circle and a three dimensional sphere is what we call a "sphere", there is no limit to the number of dimensions a sphere can have.
Which line of longitude forms a great circle with the Prime meridian?
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
Why diametrically opposite lines of longitude and equator are called great circles?
A 'great circle' is any circle on the surface of a sphere that has its center at the center of the sphere. The equator is the only parallel of latitude that's a great circle. Every meridian of constant longitude is a semi-circle, and together with the one directly opposite it, they form a great circle. The shortest distance between two points on a sphere is the piece of the great circle through them.
What figures are plane figures?
ones that can be drawn in the plane such as a triangle, circle, etc. A sphere is not one.
THE equator is the only line of latitude that is a great circle why?
The reason is because it is in the middle of the earth so it makes the biggest, most round circle, (around the Earth). it has the farthest to go around thus creating a perfectly round circle of latitude around Earth........................(i'm 13)
Why are lines of latitude and longitude called great circles?
They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.
What is the symbol for anarchist?
The universal sign for anarchist consists of an exaggeratedly drawn ''A'' with a circle drawn around it.
