Answer 1

This is your Answer!

Answer 2

Answer:

Step-by-step explanation:

in question given

diameter = 40 cm

radius = D/2

= 40/2

= 20cm.

the length of a chord is 20cm.

a/q

∆ OAB is equilateral traingle.

θ = 60°

l = 20 × 60° × π / 180°

l = 20π / 3cm

thus,

the length of the minor arc of the chord

20π / 3cm
