Rules • Every square in this grid will contain one of the numbers 1, 2 or 3. A number cannot be repeated within any row or column.

• The solid-outlined areas are called "cages." The small number in the upper-left corner of each cage is your "target number."

• The math symbol next to the target number tells us which operation we'll be using in that cage. This puzzle will only require

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
