The Answer:

I hope you have a big driveway! A regulation college court is 94 feet long and 50 feet wide, while high school courts are supposed to be 84 by 50 feet. The free-throw line (2 inches wide) is 15 feet from the backboard, which supports a basket 10 feet high at the upper edge. Into this hoop you attempt to throw a ball between 29½ and 30 inches in circumference. If you're feeling daring, try sinking one from the three-point line—19 feet, 9 inches out for amateur play, or 22 feet if you think you can hang with the pros.
