The formula for arc length is:

s= r∅

Given that ∅= 7π/4

and r= 5

Therefore, arc length s= 7π/4 *5 = 35π/4

Answer:  The required arc length will be 27.5 units.

Step-by-step explanation:  We are given to find the arc length with the following information :

\theta=\dfrac{7\pi}{4},~~~\textup{radius},~r=5.

We know that the length of an arc with angle subtended at the center α and radius of the circle r units is given by

\ell=r\alpha.

Therefore, the required arc length will be

\ell=r\theta=5\times\dfrac{7\pi}{4}=\dfrac{35}{4}\times \dfrac{22}{7}=\dfrac{5\times 11}{2}=\dfrac{55}{2}=27.5.

Thus, the required arc length will be 27.5 units.
