More on lampshades from a cone |
2019-12-14 |

Guy pose la question :
from an earlier post re; lampshade from a cone
Being math ignorant I cannot figure out how this equation makes sense
\[\frac{2\pi \times 33 - 2\pi \times 20}{2\pi \times 33} = \frac{13}{33}\]
imagine these as fractions multiplied by 360 to calculate a section of a circle to form a cone
Thx

Ellsie pose la question :
I need to make a pattern to cover an old lampshade. This is actually the bottom portion of a cone. Please help me figure out how to draw this pattern, so that we can complete our project.
