Answer 1

Do you know how to solve an annulus?

Answer 2

no.

Answer 3

c

Answer 4

You have to find the area of the whole circle, and substract it from the area of the small circle

Answer 5

The diameter of the whole circle is 5, so pi5^2= 25pi

Answer 6

Sorry I meant radius up there not diameter. The radius of the small circle is 3. So again 3^2pi = 9pi

Answer 7

So 25 - 9 leaves 16Pi

Answer 8

Yeah she's right i didn't do the hole problem

Answer 9

16 * 3.14 = ?

Answer 10

50.24

Answer 11

wth. it's not an answer choice. hold on let me redo it on paper.

Answer 12

hmm...

Answer 13

Oh, It's only asking for the area of the whole circle. So just add the diameter of both of them 3+ 2 and the answer is 25pi
so its 78.5

Answer 14

Radius* again

Answer 15

gj doe!

Answer 16

thank you! (:
