It would be letter. b....
Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r=x
r=
![\frac{x}{2 \pi }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B2%20%5Cpi%20%7D%20)
Area=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r^2
so..
A=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(
![\frac{x}{2 \pi }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B2%20%5Cpi%20%7D%20)
)^2
=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
(
![\frac{x^{2} }{4 \pi ^{2} }](https://tex.z-dn.net/?f=%20%20%5Cfrac%7Bx%5E%7B2%7D%20%7D%7B4%20%5Cpi%20%5E%7B2%7D%20%7D%20%20)
)
=
![\frac{x^{2} }{4 \pi }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E%7B2%7D%20%7D%7B4%20%5Cpi%20%7D%20)
(38-x) is perimeter
then
![\frac{38-x}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B38-x%7D%7B4%7D%20)
(
![\frac{38-x}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B38-x%7D%7B4%7D%20)
)^2
![\frac{x^{2} }{4 \pi }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5E%7B2%7D%20%7D%7B4%20%5Cpi%20%7D%20)
+ (
![\frac{38-x}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B38-x%7D%7B4%7D%20)
)^2
then you graph it and it equals
16.716 cm the circumference of the circle
150; because 6-11 is almost 180, but it’s not quite there, so it’s a little less
Answer:
B
Step-by-step explanation:
Answer:
b) median: there are 7 numbers listed; 20 is the middle number among them
range: subtract lowest from highest number 25-2=23
mean: add all the numbers together =129
mode: place numbers in order (smallest to greatest), then see which number appears the most 2, 18, 18, 20, 22, 24, 25=18
