Solve the system by the addition method <br> 4x=3y-8<br> -16x+4y=32

butalik [34]

4x = 3y - 8
4    4
x = ³/₄y - 2

      -16x + 4y = 32
   -16(³/₄y - 2) + 4y = 32
-16(³/₄y) + 16(2) + 4y = 32
      -12y + 32 + 4y = 32
      -12y + 4y + 32 = 32
      -8y + 32 = 32
   - 32 - 32
      -8y = 0
   -8 -8
   y = 0
x = ³/₄y - 2
x = ³/₄(0) - 2
x = 0 - 2
x = -2

(x, y) = (-2, 0)

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use pi on your calculator

Virty [35]

ANSWER
$V=254.47in^3$

EXPLANATION

The volume of a cylinder is given by the formula:

$V=\pi \: {r}^{2} h$

The given cylinder has diameter 6. This means that, the radius is

$r = \frac{6}{2}$

$r = 3cm$

The is height is

$h = 3r$

$h = 3(3) = 9cm$

We substitute the values into the formula to obtain;

$V=\pi \: {3}^{2} \times 9$

$V=81\pi$

$V=254.46900494$

The volume is $254.47in^3$ to the nearest hundredth
