Answer:

26pi

Step-by-step explanation:

We are given a region satisfied by the equation as

[tex]x^2 + y^2 <= 4x + 6y+13[/tex]

Rewrite this on left side and use completion of squares method

[tex]x^2-4x+y^2-6y-13\leq 0\\(x-2)^2+(y-3)^2\leq 26[/tex]

Thus the region is the interior of a cricle with centre at (2,3) and radius = square root of 26

Hence area = area of a circle

=[tex]\pi r^2 =26\pi[/tex]
