Question

In the figure, angle AOB= 30 and radius of the circle is 2 units. Find the length of chord AB

Answer 1

Answer:

where is figure? we can't explain answer without figure

Answer 2

The length of chord AB is 1.04 units.

Step-by-step explanation:

It is given that angle AOB= 30 and radius of the circle is 2 units.

Formula for length of chord is

$Chord=2r\sin (\dfrac{\theta}{2})$

where, r is radius and θ is central angle.

Substitute r=2 and θ = 30 in the above formula.

$Chord=2(2)\sin (\dfrac{30}{2})$

$Chord=4\sin (15)$

$Chord=1.035276$

$Chord\approx 1.04$

Therefore, the length of chord AB is 1.04 units.
