To find the effort distance for the claw hammer, we can rearrange the formula for mechanical advantage (MA):

\[ \text{MA} = \frac{\text{effort distance}}{\text{resistance distance}} \]

Given that the mechanical advantage (MA) is 6.0 and the resistance distance is 6.0 cm, we can set up the equation:

\[ 6.0 = \frac{\text{effort distance}}{6.0} \]

Now, we can solve for the effort distance:

\[ \text{effort distance} = MA \times \text{resistance distance} \]

Substituting in the values:

\[ \text{effort distance} = 6.0 \times 6.0 \]

\[ \text{effort distance} = 36.0 \, \text{cm} \]

Thus, the effort distance for the claw hammer is **36.0 cm**.

The correct answer is **A. 36**.
