Question

In a circle of diameter 40cm, the length of the chord is 20cm. Find the length of major arc of the Chord

Answer 1

Given :

Diameter=40cm

Length of the chord=20cm

Radius=20cm

Since radius=length of chord=20cm

Hence the formed Δle in the circle is equilateral Δle

⇒θ=60∘

We know that l=rθ

l=20×60∘×π/180∘.

l=20/π3

Thus length of the minor arc of the chord is 20/π3
