If the sectorial angle with radius 9.6 units is 75°, what is the length of the arc?

Correct option is B

Given:

Radius of the circle: 9.6 units
Angle at the center: 75°
Formula Used:
​$$\text{Length of arc} = \left(\frac{\theta}{360^\circ}\right) \times 2\pi r$$​​
Solution:
​$$\text{Length of arc} = \left(\frac{75}{360}\right) \times 2 \times \pi \times 9.6 = c$$​​
Therefore, the length of the arc is $$4\pi$$ units.
