Directions: Discus is one of the most exciting events in track and field due to the speed and distances involved. It also makes it one of the most dangerous events. Thrower and spectator safety is always a great concern.
The National Federation of State High School Associations has very strict and detailed dimensions for throwing sectors and discus cages. The sector has an angle measurement of 34.920 degrees. The actual throwing ring has a diameter of 96.5 inches.
Currently the national high school record is 234’ 3” (from the edge of the ring to where the discus lands). If we assume that this is the maximum distance to be thrown, what is the distance between the left and right out-of-bounds lines at this distance? Is this wider than a football field (160 feet)?
Explain how you determined the distance across including any necessary computations, sketches, formulas, and notes.
