the earth is a sphere but if you look at it as a 2d shape it is a circle
Yes it is. Pie = 3.14 or a half circle is 180 degree's where as a full circle is 360 degrees. I fly small aircraft an we always make incomplete circles, it used everyday in the world with engineers and mathematicians. Each quarter circle is 90 degrees, multiplied by 4 equals 360 degrees which is a whole circle. Hope this helped you. John U.
The circumference of the small circle would be 18.84.
A sphere has no plane surface. But if we consider a infinitesimal small surface of sphere then we have a plane surface and this way we have infinite planes on the sphere. Let us take the example of earth: earth is a large sphere and to human beings, so small as compared to earth, earth looks like a plane surface which is actually not reality. The same case is with the circle, circle is a closed figure which has no sides but in other way it can be considered as a polygon of infinite sides.
For the small circle of diameter 6, the circumference is 18.84.
A great circle lies in the plane that includes the center of the Earth. The plane of a small circle doesn't include the center of the Earth.
Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.
A great circle is a circle on the surface of a sphere that has the same center as the sphere, while a small circle does not share the same center as the sphere. Great circles have the largest circumference of all circles on a sphere, whereas small circles have smaller circumferences. The equator is an example of a great circle on Earth, while lines of latitude other than the equator are examples of small circles.
You can fly continuously south around the world following a great circle route. You would eventually reach the point where south and north meet at the South Pole, completing a full circle. The distance would depend on the starting point and the specific flight path taken.
An object that is stationary on the earth's surface moves in a small circle, unless it's on the equator when it moves in a great circle.

Earth's orbit around the sun is best represented by an ellipse with a very small eccentricity, which means it is almost a perfect circle. The eccentricity of Earth's orbit is about 0.0167, making it very close to a circular shape.
I think the Cherokee symbol for earth two lines slanting upwards like a pyramid with a small circle above but can't be sure.
It is a circle because, the earth is a circle, and the equator stretches all the way around the earth.
-- On the great circle, about 24,900 , just like any other point on Earth. -- On the small circle corresponding to the 40th parallel, about 19,040 miles .
The moon doesn't fly out of its orbit around the earth for the same reason that the earth doesn't fly out of its orbit around the sun, and our TV and GPS satellites don't fly out of their orbits around the earth. The mutual gravitational force between every two masses binds these small bodies to the larger bodies around which they fall in closed paths.
it means where you have previously walk on foot/bike, without flying
