Question

in a circle of diameter 40 em, the length of a chord is 20 cm. Find the length of
minor are of the chord​

Answer 1

Hey

uR AnSwER

Given

diameter =40cm

Length of the chord =20 cm

Radius =20 cm

since radius =length of chord =20cm

Hence the formed Δle in the circle is equilateral Δle

=theta =60°

we know that l=r theta

l=20 x 60°x π/180°

l=20theta /3

thus the length of the minor arc of the chord is 20theta /3
