Find The Surface Area Of The Solid Below. Round To The Nearest Tenth If Needed.

Answers

Answer 1

Answer:

1350

Step-by-step explanation:

Answer 2

Answer:

2400 ft²

Step-by-step explanation:

Base = 30x30=900

Next, we have to find the height of the triangles.

15²+20²=c²

225+400=c²

625=c²

c=√625

c=25

Now we can find the surface area of all 4 triangles.

4(1/2)(30)(25)=1500

900+1500= 2400 ft²

Answers

Answer:

14 one fourths

Step-by-step explanation:

First, we convert 7/2 into a fraction with the denominator of a four. To do this, we multiply the top and bottom by 2. 7*2 is 14, and 2*2 is 4, which gives us 14/4. This means that there are 14 one fourths in 7/2. Hope this helps!

Answer:

14 fourths

Step-by-step explanation:

Hey There!

So to solve this problem we need to divide 7/2 by 1/4

[tex]\frac{7}{2}divided by\frac{1}{4} =14[/tex]

Therefore 14 fourths can go into 7/2

Answer:

  1.13 feet

Step-by-step explanation:

We know that the sine relation is ...

  Sin = Opposite/Hypotenuse

so the length (L) of the ramp surface will be ...

  sin(angle) = 2/L

  L = 2/sin(angle)

For 18°, the ramp length will be about ...

  L = 2/sin(18°) ≈ 6.472 . . . . feet

For 22°, the ramp length will be about ...

  L = 2/sin(22°) ≈ 5.339 . . . . feet

The difference in lengths is about ...

  6.472 -5.339 = 1.133 ≈ 1.13 . . . . feet
