What is the circumference of circle p? @jim_thompson5910

OpenStudy (anonymous):

OpenStudy (alexandervonhumboldt2):

formula for circumfence is c=pi*2r or c=d*pi

OpenStudy (alexandervonhumboldt2):

where r is radius and d is diameter

OpenStudy (anonymous):

idk? plz help :(

OpenStudy (alexandervonhumboldt2):

well what do you dont understand?

OpenStudy (anonymous):

What is the circumference of circle p?

OpenStudy (alexandervonhumboldt2):

so yuor radius is 17. now substitue it into formula i gave you: c=17*2*3.14=calculate and get the anser

OpenStudy (anonymous):

ok ty

OpenStudy (anonymous):

106.76?

OpenStudy (alexandervonhumboldt2):

yes

OpenStudy (anonymous):

cool. so should it be jus 106? or all of it.

OpenStudy (alexandervonhumboldt2):

well as they dont say to round it i think dont round and type 106.76

OpenStudy (anonymous):

oh ok ty

OpenStudy (anonymous):

i got other question

OpenStudy (alexandervonhumboldt2):

ok

OpenStudy (anonymous):

what is the circumference of circle p? PB= 29m

OpenStudy (alexandervonhumboldt2):

well substitue into formula: c=r*2*pi=29*2*3.14=

OpenStudy (anonymous):

182.12?

OpenStudy (anonymous):

oh wait

OpenStudy (alexandervonhumboldt2):

yeah 182.12

OpenStudy (anonymous):

u sure?

OpenStudy (anonymous):

182 pi?

OpenStudy (astrophysics):

\[C = 2 \pi r \implies 2 (17) \pi\]

OpenStudy (alexandervonhumboldt2):

no not pi pi is already calculated. 182.12 is the final anser

OpenStudy (anonymous):

oh ok

OpenStudy (astrophysics):

Does it want you to leave pi alone or include it in the calculation?

OpenStudy (anonymous):

aiight

OpenStudy (anonymous):

heres other.

OpenStudy (anonymous):

find the length of AC? ab=36 30 degree

OpenStudy (astrophysics):

Give us a diagram.

OpenStudy (anonymous):

|dw:1428037280271:dw|

OpenStudy (astrophysics):

Know your trig ratios? If we have AB = 36, then half of that must be the radius right?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

and????? @Astrophysics
