Look Someone pls help me!

OpenStudy (anotherone):

Vocaloid (vocaloid):

S = radius * theta

OpenStudy (anotherone):

so in the middle I sub for S?

Vocaloid (vocaloid):

they give you radius and theta, you just multiply them

OpenStudy (anotherone):

0=7/9 pi would I out that in for S?

Vocaloid (vocaloid):

no

Vocaloid (vocaloid):

we need to find S

OpenStudy (anotherone):

so what do I do?

Vocaloid (vocaloid):

so you leave S alone and fill in everything else

Vocaloid (vocaloid):

S = radius * theta

Vocaloid (vocaloid):

= ?

OpenStudy (anotherone):

i don't get it

Vocaloid (vocaloid):

look at the problem

Vocaloid (vocaloid):

they want you to find s

Vocaloid (vocaloid):

They give you the radius and theta

Vocaloid (vocaloid):

so just multiply the radius * theta

Vocaloid (vocaloid):

what's the radius?

OpenStudy (anotherone):

so 18*2?

Vocaloid (vocaloid):

where is 2 coming from???

Vocaloid (vocaloid):

what's theta?

OpenStudy (anotherone):

idk

Vocaloid (vocaloid):

look at the problem

Vocaloid (vocaloid):

theta = θ = ?

OpenStudy (anotherone):

oh so would the be s=7/2 pi?

Vocaloid (vocaloid):

no

Vocaloid (vocaloid):

theta is (7/2 ) pi

Vocaloid (vocaloid):

S = radius * theta = ?

OpenStudy (anotherone):

i give up :/

Vocaloid (vocaloid):

this is not difficult

Vocaloid (vocaloid):

they want you to find s

Vocaloid (vocaloid):

you find s by multiplying radius * theta

OpenStudy (anotherone):

so times 18(7pi/2) ?

Vocaloid (vocaloid):

yes! what does that equal?

OpenStudy (anotherone):

197

Vocaloid (vocaloid):

in terms of pi

OpenStudy (anotherone):

63

OpenStudy (anotherone):

now what do i do?

Vocaloid (vocaloid):

oh whoops

Vocaloid (vocaloid):

(18)*(7/9) = ?

OpenStudy (anotherone):

14

Vocaloid (vocaloid):

good, then we just add our pi back in to get 14pi which is your answer

OpenStudy (anotherone):

s=14pi

OpenStudy (anotherone):

can help me with this one too?

OpenStudy (anotherone):

can help me with this one too?
