Answer:

G 328 ft

Step-by-step explanation:

\cos(angleBAC)  =  \frac{AB}{AC}

\cos(55°)  =  \frac{AB}{400}

AB = 229.431 ft

AB² + BC² = AC²

229.431² + h² = 400²

h = 327.659 ft ≈ 328 ft

Perform this operation and report the answer to the correct number of significant figures: What is the mass of a cube of aluminu
KIM [24]
The answer is 172.8 g.

The volume of the cube (V) is:
V = a³            (a - the side of the cube)

The density (D) <span>is quotient of mass (m) and volume (V):
D = m/V = m/a</span>³
⇒ m = D · a³
<span>

It is given:
D = 2.7 g/cm</span>³
a = 4 cm
Therefore:
m =  D · a³ = 2.7 · 4³ = 172.8 g

Please help thank you

Answer:

From the attached graphic, we can see:

(SP + PR) * PR = (WQ + QR) * QR

SP * PR + PR^2 = WQ * QR + QR^2

4 SP + 4*4 = 8 * 5 + 25

4 SP + 16 = 65

4 SP = 49

SP = 49 / 4

SP = 12.25

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
