●=> Correct option :

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

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 :

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

$=\tt r\pi = (2.6)/(2)$

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

Thus, the radius of this circle = 1.3 mm

The area of this circle :

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

$=\tt 1.3 * 1.3 * \pi$

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

Thus, the area of this circle = 1.69π

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