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

=20(60* (pi)/180)

=20(pi)/3 cm
