The sphere forms a circle in the plane. There are two bits of sphere which are spherical caps with a circular base.
A Cone.
A circle in a solid is called a cross-section.
An inscribed angle is an angle whose vertex is on the circle and whose sides are chords.
That depends on the solid that you are slicing.If the solid is a cylinder, you can make a circle by slicing horizontally,or an ellipse by slicing diagonally.If the solid has a square "base", then you can make make squares,rectangles, and even hexagons.If the solid is a cone or better yet a double cone, you can constructthe conic sections (circle, ellipse, parabola, hyperbola).===================================Answer #2:The tidiest answer to the question is: A "section" is.
A Cylinder
Cylinder
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
Using 3.14 as Pi the area of circle is: 0
A circle with a radius equal to the base of the cone. This circle will be tangential to a segment of a circle whose arc is the same length as the circle, and whose radius is the slant height of the cone.
A prism. A prism is named for its base, eg a triangular prism has a triangle for the base. If the base is a circle, the circular prism is called a cylinder.
The sphere forms a circle in the plane. There are two bits of sphere which are spherical caps with a circular base.
A Cone.
pyramid
pyramid An pyramid is a geometric solid of the shape made famous by the royal tombs of ancient Egypt. It is a solid whose base is a polygon and whose lateral faces are triangles with a common vertex
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
a base of a right solid whose height is 6 centementers shown. Find the volume. area is 28 cm and the height is 7cm
