Question

Use the Arc Length Formula for Polar Curves to calculate the arc length of the entire circle

Answer 1

where to begin? :|

Answer 2

i would just put in the answer since it doesn't know how you did it

Answer 3

@satellite73 i dont understand :|

Answer 4

it it clear that this is a circle with diameter \(11a\) ?

Answer 5

hm yes?

Answer 6

k
it is clear that the circumerence of a circle is \(\pi r^2\) ?

Answer 7

yes?

Answer 8

k then you are done with no work at all

Answer 9

arc length = circumference

Answer 10

so your saying the answer would be pi(11acostheta)^2 ??

Answer 11

radius is \(\frac{11a}{2}\) are a is
\[\left(\frac{11a}{2}\right)^2\pi\]

Answer 12

wait wait i must be kidding
circumference, not area!!

Answer 13

\[C=2\pi r\]

Answer 14

in your case \[C=2\times 11a \pi\] or
\[22a\pi\]

Answer 15

nope that is wrong too i should just shut up now
the radius is \(\frac{11a}{2}\) the area is
\[11a\pi\]

Answer 16

damn two mistakes in one easy problem
sorry

Answer 17

haha oh gosh ! ok let me try to see if that is the answer. it did suggest that i use this formula...

Answer 18

let me show you

Answer 19

@satellite73

Answer 20

you did it again! you were right !

Answer 21

you can do it that way too, but it seems like a lot of work for a simple formula you should know (and i should know too lol)
