The equation for a circle is (x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius
(x + 8)^2 + (y + 9)^2 = 169
Since the equation is -h and -k, I will rewrite in terms of -h and -k.
(x - -8)^2 + (y - -9)^2 = 13^2
The center is (-8, -9) and the radius = 13
Let me know if you need me to explain further.
The answer would be 0.02, I believe
The cube with 1 face with area 36 ft^2 has an edge of 6 ft.
The other cube has edges 2 * 6 = 12 ft long and its volume is 12^3
= 1728 ft^3 (answer).
