Answer:

Exact height = 8*sqrt(3) mm

Approximate height = 13.856 mm

=============================================================

Explanation:

If you do a vertical cross section of the cylinder, then the 3D shape will flatten into a rectangle as shown in the diagram below.

After flattening the picture, I've added the points A through F

  • point A is the center of the sphere and cylinder
  • points B through E are the corner points where the cylinder touches the sphere
  • point F is at the same horizontal level as point A, and it's on the edge of the cylinder.

Those point labels will help solve the problem. We're told that the radius of the sphere is 8 mm. So that means segment AD = 8 mm.

Also, we know that FA = 4 mm because this is the radius of the cylinder.

Focus on triangle AFD. We need to find the height x (aka segment FD) of this triangle so we can then double it later to find the height of the cylinder. This in turn will determine the height of the bead.

------------------------------

As the hint suggests, we'll use the pythagorean theorem

a^2 + b^2 = c^2

b = sqrt(c^2 - a^2)

x = sqrt(8^2 - 4^2)

x = sqrt(48)

x = sqrt(16*3)

x = sqrt(16)*sqrt(3)

x = 4*sqrt(3)

This is the distance from D to F

The distance from D to E is twice that value, so DE = 2*(FD) = 2*4*sqrt(3) = 8*sqrt(3) is the exact height of the bead (since it's the exact height of the cylinder).

Side note: 8*sqrt(3) = 13.856 approximately.

a segment is divided into two parts having lengths in the ratio of 5:3. if the difference between the lengths of the parts is 6
iren [92.7K]
2 parts.....ratio is 5:3...added = 8.....so one of the parts is 5/8 of the total...5/8x....and the other part is 3/8 of the total...3/8x

the difference is 6...
5/8x - 3/8x = 6
2/8x = 6
x = 6 * 8/2
x = 48/2
x = 24

so the total length is 24
with the longest being : 5/8(24) = 15 <==
and the shortest being : 3/8(24) = 9

Good afternoon everyone<br><br> Evaluate the expression for b = –14.<br><br> b + 4 =
Viefleur [7K]

Answer: [<em>b + 4 = -10</em>]

Step-by-step explanation: We are given the equation <em>b = -14</em> and told to, given this information, evaluate <em>b + 4 = ?</em> and find <em>?.</em> Given b = -14 we can plug in <em>-14</em> for <em>b</em> in <em>b + 4 = ?</em>. This gives us <em>-14 + 4 = ?.</em> Adding this up gives us the answer of -10. Hope that this makes sense and helps, and good afternoon to you!

-Show work-

b=-14\\(b)+4=?

(-14)+4=?

10 = ?\\?=10
