Answer 2

Answer is 11 cm

Step-by-step explanation:

• Along any section of curve, the distance between two points is called Arc length.

• Rectification/Correction of a curve can also be said as determination of length of arc (irregular segment)

• The two rays passing through the end points of an arc is called angle subtended by that arc.

Angle made by arc, $\angle \theta$ = 45°

Radius, r = 14 cm

Length of Arc of Sector = $\frac {\theta}{360} \times 2\pi r$

= $\frac {45}{360} \times 2 \times \pi \times 14$

= $\frac {1}{8} \times 4 \times 22$

= 11 cm
