how many feet is an olympic size pool
Olympic-size swimming pool There must be two spaces 2.5 m (8 ft 2 in) wide outside lanes 1 and 8 (in effect, two empty lanes).[2] The length of 50 metres (164 ft) must be between the touch pads at the end of each lane, if they are used.[2] If starting blocks are used, then there must be a minimum depth of 1.35 metres (4.4 ft) from between 1.0 metre (3 ft) from the end of the pool to at least 6.0 metres (20 ft) from the end of the pool. At all other points, the minimum depth is 1.0 metre (3 ft).[2] If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to 2.0 metres (7 ft).[2]
Three-point field goal The distance from the basket to the three-point line varies by competition level: in the National Basketball Association (NBA) the arc is 23 feet 9 inches (7.24 m) from the basket; in FIBA and the WNBA (the latter uses FIBA's three-point line standard) the arc is 6.75 metres or 22 feet 1 3⁄4 inches from the basket; and in the National Collegiate Athletic Association (NCAA) the arc is 20 feet 9 inches (6.32 m) from the basket. In the NBA and FIBA/WNBA, the three-point line becomes parallel to each sideline at the points where the arc is 3 feet (0.91 m) from each sideline; as a result the distance from the basket gradually decreases to a minimum of 22 feet (6.71 m). In the NCAA the arc is continuous for 180° around the basket. There are more variations (see main article).
