Question

help I get how to do this and got the answer but I don't have it in my answer choice. Feedback pleas

Answer 1

@JoannaBlackwelder

Answer 2

What did you get?

Answer 3

what I did was use the equatiom

Answer 4

are of sector/ pir^2= measure of arc/360

Answer 5

and when I added everything in I got the answer 50.3=x

Answer 6

so after that I figured out the area of the triangle and It was 32.

Answer 7

So I subtracted 50.3-32 and got 18.3=area of shaded region

Answer 8

but that's not one of my answer choices

Answer 9

That is what I get, but in a rounded form instead of exact.

Answer 10

yeah, so what is the equation asking???

Answer 11

For an exact form of your answer.

Answer 12

so what does that mean, I thought I did do it exact?

Answer 13

\[\frac{ 90 }{ 360 }\times64π\]

Answer 14

oh so they want the equation I used

Answer 15

Yes, it is perfect. Just don't round. Leave it in terms of π

Answer 16

Oh okay so, Would I have to diide 90 by 360

Answer 17

Right, or leave it in a fraction but simplified.

Answer 18

oh okay, so my answer would be

64 pi=1/4

Answer 19

Close, area of sector = 1/4*64pi

Answer 20

oh, okay so after this is this my answer

Answer 21

Close. You still have to subtract the area of the triangle.

Answer 22

which was 32.

Answer 23

Right.

Answer 24

so It would be 1/4*32pi

Answer 25

1/4*64pi simplifies to 16pi

Answer 26

64/4=16

Answer 27

then what would you do after that?

Answer 28

so wait the answer would be 16pi-32 because you still have to subtract the 32

Answer 29

Right. :)

Answer 30

oh gosh yes final thanks, when will you be on here till?

Answer 31

Um, I'm not sure. Why?

Answer 32
