Answer 2

●=> Correct option :

$\color{plum}\tt\bold{ A = 1.69 \pi \: mm²}$

●=> Steps to derive correct answer :

Given :

Circumference of a circle = 2.6π mm

We know that :

$\color{hotpink}\tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

Which means :

$=\tt 2 \times r \times \pi = 2.6\pi$

$=\tt r\pi = \frac{2.6}{2}$

$=\tt r \pi = 1.3 \: mm$

Thus, the radius of this circle = 1.3 mm

The area of this circle :

$=\tt \pi {r}^{2}$

$=\tt 1.3 \times 1.3 \times \pi$

$\color{plum} = \tt1.69\pi$

Thus, the area of this circle = 1.69π

▪︎Therefore, the correct option is ○ A = 1.69π mm²
