If the power is divisible by 2 and not 4, it is -1.

If the power is divisible by 4, it is 1.

If it satisfys none of those conditions, it is i or -i.

(basically, it is a pattern of i, -1, -i, and 1)

So, let's see what i^11 is. By running down the list, it satisfys only -i. Which means, i^11 is -i.

i^16 is divisible by 4, so it is 1.

Keep on going like this until you have the answer!

Since this is your homemork, I will walk you through it instead of doing it for you. So: step one

1) Find the area of the rhombus .

2) From the area, find the height using the cylinder (because it is also a paralelogram)

3) The sin of BAD is the height over 6

Good luck!

(please ask me questions if you do not understand my wording)

oops, I did not see that! Silly me...

Oh okay! Understood :)

Okay.. Here is problem 2.

It seems that the questions matches...maybe you saw the wrong answer? 

But, to save you some time, let me use my language to reword geno's answer. (none of this is my credit, it is all theirs :D, so you should thank them for creating the answer)

No problem! Let me try the other two problems...

To do this, let's find the area of the triangle and the circle.

Triangle:

bh(1/2)=A

b=8

h=4

32(1/2) = 16

Circle:

pi(r^2)=A

pi(16)=A

Area = 16pi

Probability: 16/16pi = 1/pi

@TheLovely1, I have been noticing the same thing. But, I cant see the post that answered this question . Has it been deleted, or was it privately answered? Thanks! (I'm just really curious about this issue)
