Question 1171140
.


In order for the problem could be solved, THE HEIGHT of the ring should be given.


Without it, the problem CAN NOT be solved.


Your post does not provide the height of the ring.


Therefore, the problem, as it is worded, printed, posted and presented, is a FAKE.



You may post your "THANKS" to me for pointing your error.



I am open to accept your "THANKS".
