Answer:
It is 7/8 of the circumference
Step-by-step explanation:
The formula to solve this equation is arc length ÷ 2πr
So when you plug 7π/4(radii) over 2πr, the π cancels out, and so does the r variable.
You are left with 7/4 · 1/2 which further simplifies to 7/8
Therefore the arc is 7/8 of the circumference.
