Answer 2

The length of arc is 8.25 cm.

Step-by-step explanation:

Consider the provided information.

The arc length formula is: $\text{Arc length}=\frac{\theta}{360}\times 2\pi r$

Substitute radius = 10.5 cm and central angle θ = 45°

$\text{Arc length}=\frac{45}{360}\times 2\times \frac{22}{7}\times 10.5$

$\text{Arc length}=\frac{1}{8}\times 2\times22\times 1.5$

$\text{Arc length}=\frac{1}{4}\times33$

$\text{Arc length}=8.25$

Hence, the length of arc is 8.25 cm.
