Question

using the piling method which of the following can be constructed from discs alone
a. come (not including the vertex)
b. cylinder
c. cube
d. square
e. cone (including the vertex)
f. prism

Answer 1

Answer:

My answers were a and b

Step-by-step explanation:

Answer 2

The two figures that we can make by piling discs are:

• a: Cone (not including the vertex)
• b: Cylinder.

What figures can be used from discs alone?

First, if we pile a lot of discs of equal radius, the figure formed will be a cylinder.

And also, if we pile a lot of discs of decreasing radius (such that the decrease in radius is infinitesimal, so the surface of the cone is smooth). The problem will be the vertex, as we can't make a disc in a vertex form, so a would be correct and e would be incorrect.

Then the correct options are:

• a: Cone (not including the vertex)
• b: Cylinder.
