Water flows into a conical container (radius: 12cm, height: 18cm) as shown below at the rate of 2cm^3 s^-1
calculate:
1. the rate of changes of the height of the water level.
2.the rate of change of the area of the water surface, when the height
of the water level is 6cm

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.
