Answer:

40.6 units

Step-by-step explanation:

Arc length is given by the formula ...

s = rθ

where θ is the measure of the central angle in radians.

There are 2π radians in a circle (360°), so π radians in 180°. That can be used to convert the central angle ADB to radians for use in the formula.

∠ADB = 360° -194° = 166°

∠ADB = 166° = (166/180)π radians = 83π/90 radians

Then the arc length AB is ...

length AB = (14)(83π/90) ≈ 40.561 units

The length of arc AB is about 40.6 units.

Find the center and the radius of the circle

juin [17]

Answer:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.
