Answer:
(a) (x-2)^2 +(y-2)^2 = 16
(b) r = 2
Step-by-step explanation:
(a) When the circle is offset from the origin, the equation for the radius gets messy. In general, it will be the root of a quadratic equation in sine and cosine, not easily simplified. The Cartesian equation is easier to write.
Circle centered at (h, k) with radius r:
(x -h)^2 +(y -k)^2 = r^2
The given circle is ...
(x -2)^2 +(y -2)^2 = 16
__
(b) When the circle is centered at the origin, the radius is a constant. The desired circle is most easily written in polar coordinates:
r = 2
Answer:
Each of them will get 3.375 inches of cookie.
Step-by-step explanation:
Rasputen and his three buddies are splitting a giant 18 inches cookie.
But they notice that th of it is missing.
So, the actual length of the cookie is inches.
If all the four of them get the same amount of the giant cookie then each of them will get inches of cookie. (Answer)

You would have to divide by 3.14 to find the radius squared, and to find the diameter, just add the radius plus the radius.
Answer: √14 =3.74, which is not an integer and therefore is an irrational number.
