Answer:

220ft^2

Step-by-step explanation:

In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft

In blue: 18ft - 12ft = 6ft

The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3

total rectangle area: 12ft x 18ft = 216

216 - (3 + 3) = 216 - 6 = 200            subtract 6, we added that area in

Liono4ka [1.6K]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The height that would be allowed with a ramp 43.5 feet long is ...

  h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft

The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.

__

The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.

<h3>Given:</h3>
  • h= 19 ft
  • r= 12 ft
<h3>Note that:</h3>
  • h= Height
  • r= Radius
<h3>To find:</h3>

The volume of the given cone.

<h3>Solution:</h3>

\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}

\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}

Let's solve!

Substitute the values according to the formula.

V=\frac{1}{3}×3.14×{12}^{2}×19

\large\boxed{V=2863.68 \: {ft}^{3}}

<u>Therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>cone</u><u> </u><u>is</u><u> </u><u>2863.6</u><u>8</u><u> </u><u>cubic</u><u> </u><u>feets</u><u>.</u>

Help me please!!!!! I need help with angles
Salsk061 [2.6K]

Answer:

<CFE = 28

<RPQ = 53

Step-by-step explanation:

1)

<CFE + 152 = 180

<CFE = 180 - 152

<CFE = 28

2)

Complementary means the angles add up to 90 so:

<RPQ + 37 = 90

<RPQ = 90 - 37

<RPQ = 53
