Figures are not solid.
a sphere
plane figure
A semicircle
A semicircle?
It is a plane figure, for example, a semicircle, a triangle, a kite.
No, take a semicircle, it is a plane figure and is open. Or a parabola is also open and a plane figure.
A semicircle is an example of a figure with one straight line. It is a circle that has been split along the diameter.
Geometry.a.a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center. Equation: x 2 + y2 + z2 = r2.b.the surface of such a figure; a spherical surface.or a "3D form" of a circle
A solid figure.
You have to count the lines on a solid figure
no a basketball is not a solid figure.
A semicircle is a two-dimensional shape that is half of a circle, with a flat edge as the diameter. A hemisphere, on the other hand, is a three-dimensional shape that is half of a sphere, with a curved surface. Essentially, a semicircle lies in a plane, while a hemisphere is a solid object.
