The circumference of a circle with radius $r$ is

$C=2\pi r$

So, one quarter of a circumference will be

$\dfrac{C}{4}=\dfrac{\pi r}{2}$

You radius is 6, so we have

$\dfrac{C}{4}=\dfrac{6\pi}{2}=3\pi \approx 9.42$

There are 285 seventh-graders at Greg's school.

Varvara68 [4.7K]

Answer:

124 boys and 161 girls

Step-by-step explanation:

There are 285 students total. Divide 285 by 2, you get 142.5. Since you can't have half a student, lets round it up to 143. Now, there are 19 more girls than guys, so you would subtract 19 from 143. When you do that, (143-19) you get 124. Then you take 285 and subtract 124. You get 161.

Hope this is correct!
