Want this question answered?
a cylinder has 2 round edges 1 on top and 1 on the bottom.
round. so that they could spin fast
Every shape that is round does not have edges. A shape that has sharp points and has straight lines can have edges.
because it round it rolls.
edges = 4 round base + 4 from vertices of base to apex = 8 edges corners = 4 round base + 1 apex = 5 vertices
Tablets are created with round edges so that they are less likely to stick together in the coating pan due to having a smaller surface area.
A square knot. Or a square with rounded edges, but most likely a square knot.
round
No its a CYLINDER which is ROUND that means NO EDGES
Countersinking is the forming of a shallow conical shape into a hole or fastener position to accommodate the matching conical head of a flat head screw. Generally, counterboring is the forming of a much deeper, squared bottom, cylindrical area at the origin of a hole or fastener position to accommodate and receive the head of a round-headed fastener, such as a socket head cap screw. Both processes are for the purpose of positioning the fastener such that its head is flush with or below the surface of the component which it is fastening. "Recessed" as it were.

I take into consideration that the 'bit' or point should fit securely into the socket of the screw so as not to round the edges of it.
