Find the length of AB. Leave your answers in terms of pi.
Enter a decimal rounded to the tenth.

Answer 1

Answer:

4.7 pi

Step-by-step explanation:

Length of arc AB = radius of the circle × theta(in radians)

Length of the arc = 6 × theta

Theta in radians = 140/180 × pi

Theta = (7/9)pi

Length of arc AB = 6 × (7/9)pi

Length = (42/9)pi

Length = 4.7 pi
