Answer:

Add 9 to each side of the equation.

Step-by-step explanation:

To complete the square, we need to add (b/2) ^2 to each side, where b is the coefficient of the x terms.

The coefficient of the x terms is -6

so we need to add (-6/2) ^2 = (-3)^2 = 9.

Add 9 to each side of the equation.

What is the volume of a right circular cylinder with a base diameter of 18yd. And a height of 3yd.

saveliy_v [14]

Answer:

$Volume=254$ to the nearest cubic yard.

Step-by-step explanation:

The volume of a right circular cylinder can be calculated using the formula;

$Volume=\pi r^2h$ .

The diameter of the base is given to us. We divide it into two to obtain the radius.

$r=\frac{18}{2}=9yd$ and also the height of the cylinder is $h=3yd$ .

We substitute these values into the formula to obtain;

$Volume=9^2\times 3\pi yd^3$

$Volume=243\pi yd^3$

$Volume=763.4yd^3$

(3.2 x 104) + (1.4 x 103)

Whitepunk [10]

Answer:

477

Step-by-step explanation:

(3.2 × 104) = 332.8
(1.4 × 103) = 144.2
Plug the answers above in: (332.8) + (144.2)
(332.8) + (144.2) = 477

I hope this helps!
