    Assignment:Find the solution set of inequality √(R^2-468.72)+16-（√(R^2-240.25)） ≥37.5-26.846 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         √ ( R ^ 2 - 468.72 ) + 16 - ( √ ( R ^ 2 - 240.25 ) ) ≥37.5 - 26.846         (1)
        From the definition field of √
         x ^ 2 - 468.72 ≥ 0        (2 )
        From the definition field of √
         x ^ 2 - 240.25 ≥ 0        (3 )

---

    From inequality(1)：
         R ≤ -28.604802 或  R ≥ 28.604802
    From inequality(2)：
         R ≤ -√11718/5 或  R ≥ √11718/5
    From inequality(3)：
         R ≤ -31/2 或  R ≥ 31/2

---

    From inequalities (1) and (2)
         R ≤ -28.604802 或  R ≥ 28.604802    (4)
    From inequalities (3) and (4)
         R ≤ -28.604802 或  R ≥ 28.604802    (5)

---

    The final solution set is :
         R ≤ -28.604802 或  R ≥ 28.604802
