What would the area of an actual pool be the scale from the drawing is 3: 1000

the complete question in the attached figure

we know

the pool in the drawing is 15x7.5    and the scale is 3/1000

then

if the size in the drawing  is 3----------------------> the actual is 1000

15------------------------------------< X

x=15*1000/3=5000 cms----- > 50 m

and

if the size in the drawing  is 3----------------------> the actual is 1000

7.5------------------------------------< X

x=7.5*1000/3=2500 cm--------> 25 m

the actual area of the pool is 50*25=1250 m²

the answer is 1250 m²

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.
