What is the length of the radius, r? 6 cm 18 cm 36 cm 72 cm.
Rus_ich [418]

The length of the radius of circle o is 18 cm.

<h2></h2><h2>Given that</h2>

Circle o has a circumference of 36π cm.

<h3>We have to determine</h3>

What is the length of the radius, r?

<h3>According to the question</h3>

Circle o has a circumference of 36π cm.

The length of the radius of the circle is determined by the following formula;

\rm Circumference = 2\pi r

Substitute all the values in the formula;

\rm Circumference = 2\pi r\\&#10;\\&#10;36\pi =2\pi r\\&#10;\\&#10;r = \dfrac{36\pi }{2\pi }\\&#10;\\&#10;r = 18 \ cm

Hence, the length of the radius of circle o is 18 cm.

Conditional Probability Assistance?
krek1111 [17]

Let the event A=\{ Sophomore \}, B=\{ Boy \}

The the probability of the events

P(A \cap B)=\frac{5}{12+18} =\frac{1}{6}

P( B)=\frac{12}{12+18} =\frac{2}{5}

The conditional probability

P(Sophomore|Boy)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/6}{2/5} =\frac{5}{12}

Elena has 2 fewer hats then fran. Together, they have 14 hats. Which equation represents this situation.
Free_Kalibri [48]
<h2>Greetings!</h2>

Answer:

2x - 2 = 14

Step-by-step explanation:

Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2

So then

x + x - 2 = 14

2x - 2 = 14

You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:

2x = 14 + 2

2x = 16

x = 8

So Fran has 8 hats and Elena has 6 hats.
