what is the diameter of the millennium dome
Millennium Dome The dome is one of the largest of its type in the world.[2] Externally, it appears as a large white marquee with twelve 100 m-high yellow support towers, one for each month of the year, or each hour of the clock face, representing the role played by Greenwich Mean Time. In plan view it is circular, 365 m (one metre for each day in a standard year) in diameter. It has become one of the United Kingdom's most recognisable landmarks. It can easily be seen on aerial photographs of London. Its exterior is reminiscent of the Dome of Discovery built for the Festival of Britain in 1951.
Globe Theatre The Globe's actual dimensions are unknown, but its shape and size can be approximated from scholarly inquiry over the last two centuries.[28] The evidence suggests that it was a three-storey, open-air amphitheatre approximately 100 feet (30 m) in diameter that could house up to 3,000 spectators.[29] The Globe is shown as round on Wenceslas Hollar's sketch of the building, later incorporated into his etched Long View of London from Bankside in 1647. However, in 1988–89, the uncovering of a small part of the Globe's foundation suggested that it was a polygon of 20 sides.[30][31]
