Assertion: The length of the minute hand of a clock is \( 7 \mathrm{~cm} \). Then the area swept by the minute hand in 5 minutes is \( 12 \frac{5}{6} \mathrm{~cm}^{2} \).
Reason: The length of an arc of a sector of angle \( \theta \) and radius \( r \) is given by \( 1=\frac{\theta}{360} \times 2 \pi r \)
