The figure is made up of a cylinder, a cone, and a half sphere. The radius of the half sphere is 3 inches. What is the volume of

wolverine [178]

The volume of the composite figure is 263.76 inches³

Step-by-step explanation:

The volume of a cylinder of radius r and height h is

V = πr²h ⇒ Bh

The volume of a cone of radius r and height h is

V = $\frac{1}{3}$ πr²h ⇒ $\frac{1}{3}$ Bh

The volume of a sphere with radius r is

V = $\frac{4}{3}$ πr³

∵ The figure is made up of a cylinder, a cone, and a half sphere

∵ The radius of the cylinder = 3 inches

∵ The height of the cylinder = 6 inches

∵ π = 3.14

- Use the rule of the volume of the cylinder above

∴ The volume of the cylinder = (3.14)(3)²(6)

∴ The volume of the cylinder = 169.56 inches³

∵ The radius of the cone = 3 inches

∵ The height of the cone = 4 inches

∵ π = 3.14

- Use the rule of the volume of the cone above

∴ The volume of the cone = $\frac{1}{3}(3.14)(3)^{2}(4)$

∴ The volume of the cone = 37.68 inches³

∵ The radius of the half sphere = 3 inches

∵ π = 3.14

- Use the rule of the volume of the sphere above to find the

volume of the half sphere

∴ The volume of half sphere = $(\frac{1}{2})(\frac{4}{3})(3.14)(3)^{3}$

∴ The volume of half sphere = 56.52 inches³

To find the volume of the composite figure add the volumes of the three shapes above

∵ The volume of the composite figure = 169.56 + 37.68 + 56.52

∴ The volume of the composite figure = 263.76 inches³

The volume of the composite figure is 263.76 inches³

If x>7, then |x|>7. |y|>7, so y=7<br><br><br> Valid or invalid?

Alex

$\text{if }x>7\text{, then }|x|>7$ is a valid argument

$|y|>7\text{, so }y=7$ is not a valid argument

For the first argument: $\text{if }x>7\text{, then }|x|>7$

From the definition of absolute value function

$|x|=x$ if $x\ge0$

That is every positive number is its own absolute value. Since

$x>7\implies x\ge0$ ,

we can argue that

$x>7\implies |x|>7$

so the first argument is valid

For the second argument: $|y|>7\text{, so }y=7$

From the definition of absolute value function

$|y|:=\left \{ {y\text{ if }y\ge0}\atop{-y\text{ if }y$

This means that

$|y|>7:=\left \{ {y>7\text{ if }y\ge0}\atop{-y>7\text{ if }y$

$|y|>7:=\left \{ {y>7\text{ if }y\ge0}\atop{y$

no part of the definition allow for the option $y=7$ . So the second argument is not valid.

5. answer please and thank u

Murljashka [212]

Answer:

x^3 - 2x + 4

Step-by-step explanation:

4x^2 - 2x + 6x - 10 + desiredsidelength = x^3 + 4x^2 + 2x - 6.

desiredsidelength = x^3 - 2x + 4
