Question

Find the arc length of the partial circle.

Answer 1

Answer: C=10.99

Explanation:

• It can be seen that the arc has an angle of a=90 degrees, respectively, the length of the arc can be found by the formula
• 
  `\bf C=\frac{2\bf {\pi} r}{360} \cdot \alpha=> (2\cdot 3,14\cdot 7 )/(360) \cdot 90=\boxed{\bf 10.99}`
