If radii of two concentric circles are 4 cm and 5 cm, then the length of chord of one circle which is tangent to the other circle is

• 3

• 6

• 9

• 1

In Fig., if ∠AOB = 125°, then ∠COD is equal to

• 55

• 45

• 35

• 65

If Fig., AB is a chord of the circle and AOC is its diameter such that ∠ACB = 50°. If AT is the tangent to the circle at the point A, the ∠BAT is equal to

• 62.5

• 60
