the length of an arc is given by =>
[tex]\frac{\emptyset}{360}X\frac{2\pi r^{}}{1}[/tex]
the radius is 10cm
and the angle = 45 degrees
pi = 22/7
length =
[tex]\begin{gathered} \frac{45}{360}X\frac{2\pi\text{ X 10}}{1}= \\ \Rightarrow\frac{900\pi\text{ }}{360}=\text{ }\frac{900\text{ X 22}}{360X7} \\ \Rightarrow\text{ 7.8534cm} \\ \text{LENGTH OF ARC = 7.85cm} \end{gathered}[/tex]
