Answer:
The fraction of Arc to circle is 85/88
Step-by-step explanation:
2π radian makes an circumference on circle which is 2πr.
7π/4 radian makes
(7π/4) * (1/2π) * (2πr)
= 7*22*r/4*7 = 11r/2.
This arc has 2 radius to close, which means,
Circumference of arc = 11r/2 + 2r = 15r/2.
Circumference of circle = 2πr
Fraction of arc circumference to circle = (15r/2) * (1/2πr)
= 85/88.
The fraction of Arc to circle is 85/88
