What is an example of 2 and 3 dimensional shapes?
Well two dimensional means a flat shape, like a square, or a circle. A three dimensional shape means you can hold it, like the 3-D version of a square is a cube, and a 3-D circle is a sphere.
If the radius of a circle is doubled what happens to its volume?
A circle does not have volume since it is a 2 dimensional shape. Volume requires 3 dimensions.
Is semi circle a 2D or 3D?
A semicircle is a two-dimensional (2D) shape. It is a closed curve that divides a circle into two equal parts, with one straight edge and one curved edge. In contrast, three-dimensional (3D) shapes have depth, width, and height, such as cubes, spheres, and pyramids.
What is the volume of a circle if its radius equals 4?
There is no volume in a circle but volume can be found in a sphere. The question should be rephrased. A circle is a two dimensional shape, so it cannot have a volume which is a characteristic of a three dimensional shape.
What is the difference between spherical and circle?
A sphere is a three dimentional shape, a circle is a two dimentional shape. You can't pick up a circle, it can only be drawn. In differential geometry, a one dimensional sphere is a point, a two dimensional sphere is a circle and a three dimensional sphere is what we call a "sphere", there is no limit to the number of dimensions a sphere can have.
