which circumference of the basketball ring are you trying to calculate? 2d or 3d -"... 3d
you have to know how to use these: shading, 1 point perspective, and 2 point perspective.
Yes
its if you take a 3D figure and open all of its sides and draw it in 2D so that if you folded it all back up again you would have the original 3D object
You cannot draw a 3d shape. What you can draw, though, is a two dimensional projection of a 3 dimensional shape.
Yes you can draw the nets of 3D objects on graph paper
Do you mean on a piece of paper? If so, you have to add perspective to it. One way to do that is to draw a background. Another way is to give your object a 3D illusion through techniques such as shadowing and shading.
Well, a 2D object has only length and width, but a 3D object has length, width, and depth.
a 3d object is a object that isn't flat. for instance, a square in 3d form would be a cube
The circumference is tripled.C=pi*d, so pi*(3d) = 3C, where d is diameter and C is circumference.
It is one of several methods to draw a 3D object (like a globe) on a 2D surface (like a piece of paper).See related links.
a 2D object is is flat and on the other hand a 3D object is bulgy
