An Olympic sized swimming pool of uniform depth measures 50 meters by 21 meters. The bottom of the pool is treated with a sealer, and one galloon of the sealer covers 3000 sq feet of surface. How many galloons will be required for the job? Round to the nearest whole galloon.

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.
