Find the area of the region satisfying the inequality x^2 + y^2 <= 4x + 6y+13 + 10x +2y
When you move every term to the left-hand side, you get x2+y2−14x−8y−13≤0.
Complete the squares and you will get .
So this is actually just the area enclosed by the circle centered at (7, 4) and with radius . Can you take it from here?
