what is distance of free throw line from basket
Basketball court The key, free throw lane or shaded lane refers to the usually painted area beneath the basket; for the NBA it is 16 feet (4.9 m) wide, for the NCAA it is 12 feet (3.7 m) wide; for both instances it extends 15 feet (4.6 m) from the backboard. At the top of the rectangle is the free throw line, behind which players shoot uncontested shots when they're fouled. A circle is drawn around the free-throw line with a 6 feet (1.8 m) radius; this is used for jump ball instances, as is done at the center circle. Two 6-inch hash lines, 3 ft from the free throw lane line and 5 ft 8 in from the free throw line, show the lower defensive box linked to the restricted area.
Three-point field goal Used only in conference play for several years, it was adopted by the NCAA in April 1986 for the 1986–87 season at 19 ft 9 in (6.02 m)[23][24][25][26] and was first used in the NCAA Tournament in March 1987.[27] The three-pointer was adopted in women's basketball on an experimental basis for that season at the same distance, and made its use mandatory beginning in 1987–88.[28] In 2007, the NCAA lengthened the men's distance by a foot to 20 ft 9 in (6.32 m), effective with the 2008–09 season,[29] and the women's line was moved to match the men's in 2011–12.[28] American high schools, along with elementary and middle schools, adopted a 19 ft 9 in (6.02 m) line nationally in 1987, a year after the NCAA.[30] The NCAA used the FIBA three-point line (see below) in the National Invitation Tournament (NIT) in 2018.[31]
