Molly's milk company wants to repaint the barrels in which the milk is stored. the workers need to know how much area they will be painting so that they can order the correct amount of paint. if a milk barrel is 8 feet tall with a radius of 8 feet, what is the surface area of one barrel?

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.

probably the last option
