Let J be the region in the first quadrant bounded by the x-axis, the curve y = √x, and the line x = 9. 1. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about x-axis.
2. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about the line x = 9.

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.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
