The area of a rectangular shape is found my multiplying the base x height. Since squares have the same measure all the way around the base must be equal to height so b x h for a square is equal to (b x b)=b^2 or (h x h)^2 they are the same to using b for base we have b^2=196 so sqrt(196) = each side is 14sqft. To find the perimeter we just add all the sides to get (14+14+14+14) or (14*4)= 56sqft.

Find the area of the region enclosed by the graph of $x^2 + y^2 = 2x - 6y + 6$

Luda [366]

Answer:

16π ≈ 50.27 square units

Step-by-step explanation:

The equation is that of a circle of radius 4. The area of a circle is given by ...

A = πr²

A = π(4²) = 16π ≈ 50.27 . . . . square units

_____

The equation can be put into the standard form for a circle to find its radius.

(x^2 -2x) +(y^2 +6y) = 6 . . . . collect variable terms on the left

(x^2 -2x +1) +(y^2 +6y +9) = 6 + 1 + 9 = 16 . . . . . complete the squares

(x -1)^2 +(y +3)^2 = 4^2 . . . . . the radius is 4

Compare to the form ...

(x -h)^2 +(y -k)^2 = r^2 . . . . circle of radius r centered at (h, k)
