For statement 1,
We know area of the circle = π \(r^2\)
= π \((\sqrt{7})^2\)
= 7π
In Statement 2,
We know area of the circle = π \(r^2\)
= π \((\sqrt{14})/2)^2\) (Since here diameter is given so we divide it by 2 to get the radius)
= \(\frac{14}{4}\) π
= \(\frac{7}{2}\) π, which is less than statement 1
Hence option A

B has radius sqrt14/2<sqrt7
that gives area A> area B
that gives area A> area B
