Answer: [tex]\frac{85}{2} \pi[/tex]
Step-by-step explanation:
Circumference is 50 because [tex]2\pi (25)= 50\\[/tex]. BCA= [tex]2\pi -\frac{3}{10}\pi[/tex]. Arc length over circumference = arc measure over radians in a circle. So arc length over [tex]50\pi[/tex] = [tex]\frac{\frac{17}{10}\pi }{2\pi }[/tex]. Arc length = [tex]\frac{17}{10}\pi *\frac{50\pi }{2\pi }[/tex]. Which then equals [tex]\frac{85}{2} \pi[/tex].
