The equation that expresses the relationship between the variables is T = krs³. Using the given values, we can plug in and solve for k: 
11ebfdc1_ec18_b6d8_abe3_1f4af5b3e826_TBX8727_11 = k(11ebfdc1_ec18_b6d9_abe3_b51720305f5b_TBX8727_11)(11ebfdc1_ec18_b6da_abe3_b12a0935eaed_TBX8727_11)³ 
Simplifying this expression and solving for k, we get:
k = 11ebfdc1_ec18_dded_abe3_133be66878a2_TBX8727_11 
Therefore, the best choice is C.
