Picture circle O as the cross section of the drum. The chord representing the grilling surface is PQ, with midpoint M.

The depth of the BBQ is the radius of the drum, plus the length of segment OM.

You can determine the length of OM using right triangle OMP because you know the lengths of OP and MP.
