$$\triangle$$, $$\bigcirc$$, and $$\square$$ each represents a number. If $$\triangle +\triangle +\triangle =60$$, $$\square \times \triangle =260$$, and $$\bigcirc \div \square =6$$, what is the value of $\bigcirc$?  $$\triangle$$, $$\bigcirc$$, 和 $$\square$$ 各代表一个数$$.$$ 若 $$\triangle +\triangle +\triangle =60$$, $$\square \times \triangle =260$$, 且 $$\bigcirc \div \square =6$$,~ $\bigcirc$的值为?
