How many holes does a hollow cylinder have?
It is a hollow cylinder with 2 openings at either end . However if we flattened it into a disc, there would only be one area that is completely “punched out”, which means one hole by this definition.
Does cylinder have one or two holes?

Does a hole have to have an end?
A hole needs two ends to be a hole...” “It has one. Imagine trying to make it have fewer; If you plugged the hole it would have none.”
How many holes has a straw got?

How many holes does a donut have?
Topologically, that would be the same as S1 × D, where D is a disc (imagine gluing a disc to each point around a circle). This is actually true since the disc can be deformed to an interval–just squash it to a diameter. The assertion is then that a donut “clearly” has one hole .
