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.
Ten-pin bowling The 41.5-inch-wide (105 cm),[1] 60-foot-long (18 m)[1] lane is bordered along its length by semicylindrical channels called "gutters", which are designed to collect errant balls. The overall width of the lane including the channels is 60 1⁄8 inches (153 cm).[1] The narrow lane prevents bowling a straight line at the angle required to consistently carry (knock down) all ten pins for a strike. Most skillful bowlers will roll a side spinning (hook shape reaction) ball to overcome this. A foul line is marked at the seam of the start of the lane and end of the approach. If any part of a bowler's body touches the line itself or beyond (anywhere on the actual lane surface or any adjoining areas including walls and other lanes) after the ball is delivered, the bowl is a foul and any pins knocked over by that delivery are scored as zero (0). The bowler is allowed one shot at a new rack of ten pins if s/he fouled on the first roll of a frame, and if all ten pins are knocked down on this shot, it is scored as a spare. Behind the foul line is an "approach" approximately 15 feet (5 m) long used to gain speed and leverage on the ball before delivering it. 60 feet (18 m) from the foul line, where the lane terminates, it is joined to a roughly 36-inch (91 cm) deep by 41.5-inch (105 cm) wide surface of durable and impact-resistant material called the "pin deck", upon which each rack of pins is set.
