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 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 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.
Can a circle always be drawn around a four-sided shape?
If you mean can a circle always be drawn round a quadrilateral so that the quadrilateral is enclosed within the circle then yes as long as the diameter of the circle is large enough. If you mean can a circle always be drawn around a quadrilateral so that it passes through all vertices then only if the opposite angles of the quadrilateral add up to 180o - such quadrilaterals are called cyclic quadrilaterals.
How can you find the normal to a point on a sphere at any arbitrary point on the sphere?
It's the extension of the sphere's radius drawn to that point.
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 International Date Line forms a great circle with the Prime Meridian. A great circle is the largest possible circle that can be drawn around a sphere.
Why diametrically opposite lines of longitude and equator are called great circles?
Diametrically opposite lines of longitude and the equator are called great circles because they are the largest circles that can be drawn on a sphere. These circles divide the sphere into two equal halves and pass through the center of the sphere, making them great in size and significance.
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?
Lines of latitude and longitude are called great circles because they are the largest circles that can be drawn on a sphere, having a center at the sphere's center. Great circles are important for navigation as they represent the shortest distance between two points on the surface of a sphere.
What is the symbol for anarchist?
The universal sign for anarchist consists of an exaggeratedly drawn ''A'' with a circle drawn around it.
