What type of meetings are held where participants are not physically present in one location but are connected via voice and video?

The most accurate choice here is virtual meetings, which encompass any gathering where participants communicate and collaborate without being in the same physical space, typically using technology such as video and audio conferencing tools.

Videoconferencing specifically refers to a real-time video connection between participants, emphasizing visual interaction. While this is a common method used in virtual meetings, it is just one type of technology used to facilitate the overall concept of virtual meetings.

Webinars typically refer to presentations or seminars conducted over the internet, focusing on a presenter delivering information to an audience rather than an interactive meeting format.

Hybrid meetings are a blend of in-person and virtual participation, allowing attendees to join either physically at a specific location or remotely. This definition extends beyond just voice and video connections, incorporating elements of both formats.

Thus, while videoconferencing is indeed a critical component of virtual meetings, the broader term "virtual meetings" better captures the essence of gatherings that use any form of technology to connect participants remotely.
