Let's be very careful here: The "great circle" of a sphere is a circle that lies on the surface of
the sphere, so there's no way the great circle can "pass through" the sphere's center.
However, in order for the circle to be a "great circle", its center must be the center of the sphere.
Sure.A circle is the shape of every possible CUT through a sphere with a flat knife.
Every cross-section of a sphere is a circle.
The segment that passes through the center of a circle and has endpoints on the circle is called a diameter. It is the longest chord of the circle and divides it into two equal halves. Every diameter is composed of two radii, extending from the center to the circle's circumference at each endpoint.
It is the center of the circle
A circle has a round shape in which every point on the circle is the same distance from one point called "the center". The center of a circle is not on the circle.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
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.

A radius of 2 meters refers to the distance from the center of a circle or sphere to its outer edge. This means that if you were to draw a circle with a radius of 2 meters, every point on the circle would be exactly 2 meters away from its center. The diameter of such a circle would be 4 meters, as the diameter is twice the radius.
Every diameter of the circle.

A circle has a round shape in which every point on the circle is the same distance from one point called "the center". The center of a circle is not on the circle.
The precise definition of the word 'centres' is the middle point of a circle or a sphere. This means the point is an equal distance from every point on the circle/sphere.
No. The chord is a diameter only if it passes through the center of the circle. In that case,it's also the longest that any chord can possibly be in that circle.
