The point (5,-6) lies on a circle and the center of the circle is at the point (5,-8).
mario62 [17]

Answer:

A.  

(x - 5)^2 + (y + 8)^2 = 4

Step-by-step explanation:

The equation for a circle in center radius form is

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

We need to determine the radius, from the two points which is the distance

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

  = sqrt( (5-5)^2+( -8--6)^2)

  = sqrt(0+ (-8+6)^2)

  = sqrt( 0+(-2)^2)

  = sqrt(4)

  = 2

The radius is 2 and the center is (5,-8)

(x-5)^2 + (y--8)^2 = 2^2

(x-5)^2 + (y+8)^2 = 4

tamaranim1 [39]
How much left is the simply the area.

Area = length * width

Area = 7 feet * 2  2/9

Area = 7 * 20/9 = 140/9

Area = 140/9  square feet.
