Use Pythagoras
3^2 = r^2 + (2 + r)^2
9 = r^2 + 4 + 4r + r^2
2r^2 + 4r = 5
Complete the Square
r^2 + 2r = 5/2
(r + 1)^2 - 1^2 = 5/2
(r + 1)^2 = 5/2 +1 = 7/2
r + 1 = +/- sqrt)7/2)
r = -1 +/-sqrt)7/2)
r = -1 +/- sqrt(3.5
r = -1 +/- 1.8708....
r = -2.8708.... (Unresolved!!!! Philosophically you cannot have a negative length).
& r = 0.8708.... The answer!!!!
The discus throw is measured from the inner edge of the throwing circle to the point where the discus first lands. The farthest mark reached by the edge of the discus is considered the final measurement for the throw. The measurement is typically taken in meters or feet.
The diameter is 8 feet, circumference 25.12, area 50.24

The diameter of the discus ring is 2.5 meters. This measurement is standard for discus throwing competitions and ensures a uniform and fair playing field for all athletes. The ring provides a designated area from which competitors must release the discus.
I believe it is 74 meters
