What is the geometric mean of 6 and 11?

The geometric mean of two numbers, ( a ) and ( b ), is calculated using the formula ( \sqrt{a \times b} ). For the numbers 6 and 11, the geometric mean is ( \sqrt{6 \times 11} = \sqrt{66} ). This simplifies to approximately 8.12. Thus, the geometric mean of 6 and 11 is about 8.12.
