A heptagon has 5 triangles.
10 triangles....
You can approximate the surface area by lots of triangles (base of the triangle on the base of the cone, and tip of the triangle at the tip of the cone), and analyze what happens when the triangles get narrower and narrower.
An infinite of infinitely small ones. You would need to use calculus to calculate the volume of a cone given a single triangular cross-section.
ice cream cone is the easy-est one i know ice cream cones are cones not triangles
It could be a cone
Because they are both triangles and they are both 3 dimensional!
there are 27 triangles in a triangle
There are 15 triangles in a 17-agon
15 triangles!!!!!!!!!!
no triangles
it has 13 triangles
There are no triangles.
