Answer :
The radius of the circle = 10cm
Intercepted by angle =20
Expression for the Arc of the circle is
[tex]\begin{gathered} \text{Arc Length=2}\pi\text{Radius}\frac{\theta}{360} \\ \text{Substitute the value of Radius =10cm \& }\theta=20 \\ \text{Arc Length=2}\pi(10)\frac{20}{360} \\ \text{Arc Length=}\pi(10)\frac{1}{9} \\ \text{Arc Length=}\frac{3.14\times10}{9} \\ \text{Arc Length=}3.488\text{ cm} \end{gathered}[/tex]The length of Arc Length is 3.488
Answer : 3.488 cm
