Question

what do we get if we divide a circles area by its circumfrence

Answer 1

cuz i dont understand this question

Answer 2

\[area=\pi r^2\]
\[circumference=2 \pi r\]
\[\frac{area}{circumference}=\frac{\pi*r*r}{2*\pi*r}\]
\[=r/2\]

Answer 3

Here's the formula for area:
\[A=\pi r^2\]
Here's the formula for the circumference:
\[C=2\pi r\]
Now just divide them:
\[(\pi r^2)/(2\pi r) = (r^2)/(2r) = r/2\]

Answer 4

so i divide 20 by ?

Answer 5

nope
r/2=area/circumference
r/2=20
r=2*20
r=40

Answer 6

thx bro i got it yea
