Find the volume of the shaded figure by subtracting the smaller volume from the larger

a.

Step-by-step explanation:

a.

Volume of the shaded figure =

b. expressed in factored form:

Look for the term that is common to 9a³ and 9ab², then take outside the parenthesis.

your answer is the frist one

hop i

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.
