The circumference of a circle is 19.468 meters find the radius of the circle?

3.1 m

Step-by-step explanation:

Okay, to find the circumference of a circle the formula is c = 2 3.14 x r.

R represents the radius.

So, you are trying to find the radius of a circle not the circumference of a circle. We know what the circumference is (19.468).

Therfore you would multiply each answer choice by 2 then by 3.14.

3.1 x 2 = 6.2

6.2 x 3.14 = 19.468

19.468  = 19.468

So your answer is 3.1 m.

To double check all your math you would do this to each answer choice.

I hope that this helped! :)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
