how many edges are there in a cone and a cylinder?

Answer 1

I will leave u to count them :))
---------------
circular shapes has problem in counting their edges assome consider circle as have enumerable sides
but oher than this idea we can consider cone have 1 edge, cylnder 2 edges

Answer 2

In each case, the only edges are the circles -- one in the case of the cone, two in the case of the cylinder.

That's unless your teacher is using a definition of "edge" that involves vertices. If so, then maybe s/he thinks neither has any edges.

Answer 3

cone 1 edge
cylinder 0 edge
