A sphere is ball-shaped and has the same dimension in all directions, so a nickel can't be a sphere.
However it's technically not a circle, either, because a circle is a 2-dimensional object while coins are 3-dimensional. While its cross-section is a circle, a nickel is actually a cylinder.
A 2D sphere is a circle.
No.

Sure.A circle is the shape of every possible CUT through a sphere with a flat knife.
if it a 2D shape it would be a circle,but if it is a 3D shape it would be a sphere
It is a sphere.
it's a semi-sphere circle is to semi-circle as sphere is to semi-sphere
A sphere is a 3-D shape, while a circle is a flat, 2-D shape.

A circle or a sphere
No.

Sure.A circle is the shape of every possible CUT through a sphere with a flat knife.
A circle or a sphere has no verticals because it has a smooth surface.
if it a 2D shape it would be a circle,but if it is a 3D shape it would be a sphere
A circle or a sphere could fit the given description
