MA_775_DIABLO [31]

Good morning,

Answer:

<h2>r = 4 cm</h2>

Step-by-step explanation:

V = h × (base area)

  = 12 × (π×r²)

then 192π = 12π×r²

Then 192 = 12×r²

Then r² = 192÷12 = 16

Then r = √16 = 4.

Which angles form a linear pair?
Igoryamba

A linear pair of angles has a common side, and the vertex is on the line designated by the points denoting the non-common sides.

Consider the first choice:

... the common sided is RL, and the other two points are P and M. Point R (the vertex of the angles) is not on line PM. (In fact, line PM is not shown on the diagram.)

In the second choice, the given angles do not have a common side. (They are actually "vertical" angles.)

In the 3rd choice, the common side is RN, and vertex point R is found on line MO. These angles <em>are</em> a linear pair:

... - MRN and NRO

If you know the names of the remaining eight eight students in the spelling​ bee, what is the probability of randomly selecting
STALIN [3.7K]
Assuming that there are 8 names that are going to be used for a random order; 

First, let's try to figure out how many possible ways the names can be arrange: 

=8 choices x 7 choice x 6 choices x 5 ... x 1 choice (if you select person A to go first, they cannot be second as well, so that is why 8 choices is multiplied by 7 instead of 8) 

This can also be written as 8! 

The specific way that a random set of names is chosen by you and actually chosen is 1. Each name has a specific order, in each term so there can only be one possible way. 

Therefore, P(order being chosen)=1/8! 

Hope I helped :)
