The mechanical advantage (MA) can be calculated using the formula:
\[
MA = \frac{\text{Radius of Wheel}}{\text{Radius of Axle}}
\]
Given that the radius of the wheel is 49 cm and the radius of the axle is 7 cm, we can substitute these values into the formula:
\[
MA = \frac{49 \, \text{cm}}{7 \, \text{cm}} = 7
\]
Therefore, the mechanical advantage is **7**.
