How does the volume of a cone change if its radius and height are both tripled

The volume formula could be re-written to help understand this, as V = π*3r^2*3h. If you solve for this, you can conclude that the volume would be multiplied by 27.

The five values for a data set are:
dem82 [27]

Answer:

The box-and-whisker plot for the given question is as shown at the attached figure.

Minimum = 11

Lower quartile = Q1 = 12

Median = Q2 = 23.5

Upper quartile = Q3 = 27

Maximum = 33

<u>So, according to the given data and the figure:</u>

  • The box will go from <u>12 to 27</u>                ⇒ Q1 to Q3
  • A line dividing the box will go at <u>23.5</u>   ⇒ Q2
  • The left whisker will go from <u>11 to 12</u>     ⇒ Minimum to Q1
  • The right whisker will go from to <u>27 to 33</u>  ⇒ Q2 to Maximum

Answer:

  Use the Pythagorean theorem: (5/8)^2 +(3/2)^2 = (13/8)^2 ⇒ right triangle

Step-by-step explanation:

Check to see if the numbers satisfy the Pythagorean theorem.

  (5/8)^2 + (3/2)^2 = (13/8)^2

  25/64 + 9/4 = 169/64

  25/65 +144/64 = 169/64 . . . . . . . true. The triangle is a right triangle.

__

If a, b, c represent the lengths of the sides, least to greatest, then ...

  a^2 + b^2 > c^2 . . . . acute triangle

  a^2 + b^2 = c^2 . . . . right triangle

  a^2 + b^2 < c^2 . . . . obtuse triangle

_____

<em>Additional comment</em>

A triple of integers that satisfy the Pythagorean theorem (form a right triangle) is called a "Pythagorean triple." One you see often, and that has the special property that it is <em>the only triple that is an arithmetic sequence</em> is (3, 4, 5). A couple of other common ones are (5, 12, 13) and (7, 24, 25).

Any of these can be scaled by a common factor to make sides of a right triangle. Here, we have (5, 12, 13) scaled by a factor of 1/8 to make (5/8, 12/8, 13/8) = (5/8, 3/2, 13/8) — the numbers in the problem statement.

If you're aware of these common triples, you can check to see if they are being used in any right-triangle problem you may run across. Recognizing that one of these applies can save you the effort of working out the squares and/or root that would otherwise be involved.
