No, of the sphere
NO it is not.
A sphere is three dimensional, a circle is not. So a tennis ball is sphere not a circle You can draw a circle on paper but is is not a sphere.
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.
no, it is sphere is not a perfect circle. because sphere is 3dimensional figure and circle is 2 dimensional figure
No, it's 2D. Anything that fits on a piece of paper (for example) is 2D. The 3D equivalent of a circle is a sphere.
Sphere
It is the diameter of the circle or the sphere
A sphere is a 3D circle. Like a baseball.
sphere
Square is to cube as circle is to.......sphere
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.
