Answer:
The arc length is
Step-by-step explanation:
2πr(angle/360)
segment Bc is the diameter which means it's also supplementary.
If it's supplementary it should be 180 degrees.
Currently we know that arc AB is 30 degrees
180 - 30 = 150 degrees
angle ADC = 150 degrees.
plug in 150 in the angle it should be like 2πr(150/360).
the diameter is 7in and to find the radius it would be half of 7 which is 3.5in
2π(3.5)(150/360) = 9.1630
Make sure to round.
Final answer: 9.2cm
