Answer 2

what's the area of the blue circle?

Answer 3

26.4?

Answer 4

that's the radius I think

Answer 5

either that or the diameter

they didn't label the drawing too well

Answer 6

2189.56 ?

Answer 7

I think because the line goes through the whole circle, 26.4 is the diameter

Answer 8

oh ok

Answer 9

how do i find the area of the blue circle?

Answer 10

area = pi*r^2

r = radius

Answer 11

radius = diameter/2

Answer 12

1.6328?

Answer 13

how did you get that

Answer 14

26.4/2= 26 2/5
3.14*26 2/5^2=6.5312

Answer 15

oops. I am not sure.. did i get it right now?

Answer 16

26.4/2= 26 2/5 is false

Answer 17

26.4/2= 13 1/5

Answer 18

it should be 26.4/2= 13.2

your calculator is in one strange mode, idk

Answer 19

yeah 13 & 1/5 = 13.2

Answer 20

so 3.14*13.2^2= 547 71/625?

Answer 21

or 547.1136? my calc is weird

Answer 22

yeah roughly 547.1136

Answer 23

that's the blue circle area

Answer 24

in terms of pi, it is 174.24pi

Answer 25

ok

Answer 26

do the same with the larger circle

Answer 27

3.14*8.8^2?

Answer 28

8.8 isn't the radius, but it's part of it

Answer 29

what is the radius?

Answer 30

radius of larger circle = (radius of smaller circle) + 8.8

Answer 31

try to imagine the smaller circle erased for a second

Answer 32

so 555.9136?

Answer 33

547.1136+8.8= 555.9136

Answer 34

547 is way too big

Answer 35

the smaller radius was 13.2

Answer 36

oops, 13.2+8.8=22

Answer 37

use that radius to find the area

Answer 38

1519.76

Answer 39

pi*r^2
3.14*22= 1519.76 right?

Answer 40

22^2

Answer 41

now you subtract the two areas

Answer 42

1519.76-547.1136= 972.6464

Answer 43

so 973.1 ft2 (:

Answer 44

Find the measure of <3

120°
30°
45°
90°

Answer 45

isn't it 90 degrees?

Answer 46

close

Answer 47

you bisect it though

Answer 48

45 degrees?

Answer 49

yeah

Answer 50

Find the measure of
is it 45?

Answer 51

wait 60?

Answer 52

your question is incomplete

Answer 53

oops. find the measure of <1

Answer 54

why 60

Answer 55

i did 360/6

Answer 56

good

Answer 57

ok. i cant remember how to do this

What is the area of the circle if XY = 17 in.?

Answer 58

do i * 17 by pi?

Answer 59

its my last question i need help with

Answer 60

what is the radius

Answer 61

i forget how to find it uhm..

Answer 62

well XY = 17 is the diameter

Answer 63

ohh 17/2?

Answer 64

17/2= 6.5?

Answer 65

3.14*6.5= 20.410?

Answer 66

17/2 is not 6.5

Answer 67

you're thinking of 13/2

Answer 68

17/2= 8 1/2

Answer 69

ohmy idk y i put 6, my calc says 8

Answer 70

3.14*8.5= 26.69

Answer 71

and then you have to square the radius

Answer 72

8.5 right?

Answer 73

72.25

Answer 74

or 72 1/4

Answer 75

multiply 72.25 with pi to get the area

Answer 76

oh yeah, 226.865

Answer 77

that number is big though. what do i do next i forget?

Answer 78

what are your answer choices?

Answer 79

17π in2
72.25π in2
36.75π in2
8.5π in2

Answer 80

so just undo that last step we did

Answer 81

and leave it in terms of pi

Answer 82

ohh ok

Answer 83

thanku so much!!

Answer 84
