Answer:

21.82\ ft

Step-by-step explanation:

we know that

The circumference of a complete circle is equal to

C=2\pi r

In this problem we have

r=10\ ft

substitute

C=2\pi (10)=20 \pi\ ft

Remember that

An angle of 360\° subtends the arc length of a complete circle

so

by proportion

Find the arc length for an angle of 125\°

\frac{20 \pi}{360}\frac{feet}{degrees}=\frac{x}{125}\frac{feet}{degrees}\\ \\x=125*(20\pi )/360\\ \\x=21.82\ ft
