Di. of the circle = 40 cm
then rad. = 20 cm
now chord = 20cm
the triangle formed is an equilateral triangle with each side = 20cm
Θ = 60°
now length of the arc is I = rΘ
= 20(60°*п(pi) /180°)
= 20π/3cm
hope this HELPS U WITH THE IMAGE GIVEN BELOW!!!!!!!!!!!!!!!

Length of the minor arc=radius*angle made
                                      =20(60* (pi)/180)
                                      =20(pi)/3 cm
