The area of a circle is 18.1 km^2. Find the radius of the circle in kilometers rounded to the nearest tenth. Use 3.14 for PI, and enter the number only.

2.4

Step-by-step explanation:

area = pi* r^2

18.1 /3.14=r^2

5.76 =r^2

Now root square

2.4 km

Step-by-step explanation:

πr²=18.1 km²

18.1/3.14=5.76km²

576/100

24/10=2.4km

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
