Step-by-step explanation:
The length of TVD₂ is just under a tenth of a millimeter. It is quoted to only two digits, because π (pi) is known to only two digits.It seems like your question is related to a specific context or diagram involving TVD₂ (possibly referring to Total Vertical Depth 2 in a drilling context or something similar). To provide a meaningful explanation and a numerical answer, I would need more details about the context, any provided diagram, or additional information.
