Answer 2

\[\frac{ r^2 }{ 2 }(\frac{ \pi }{ 180 }c-\sin(c))\]

Answer 3

thats the formula. so lets plug in the values

Answer 4

do I put 8 in for r2?

Answer 5

\[\frac{ 8^2 }{ 2 }(\frac{ \pi }{ 180 }*120-\sin(120))\]

Answer 6

so yes

Answer 7

i don't have a graphing calculator. but would it be 4(3.14/180 8120-sin(120))

Answer 8

is it 7.5?

Answer 9

without a graphing calculator, you woul do 8^2 which is 64 divided by 2 to get 32. so do 32(3.14/180*120-sin(120) yes

Answer 10

but "/" meaning "divided by

Answer 11

66.1? that's what I got but that's not an answer

Answer 12

i got 39.3

Answer 13

alright well thank you!!

Answer 14

What is the area of the circle if XY = 10 ft?
A) 20pi ft^2
B) 10pi ft^2
C) 5pi ft^2
D) 25pi ft^2

Answer 15

anytime

Answer 16

area is pi*r^2. it gives diameter, 10, si divide that by 2 to get 5

Answer 17

5^2= ??? multiply that by pi

Answer 18

multiply 25 by pi?

Answer 19

yes

Answer 20

78.5

Answer 21

itd be d. i didnt know it was supposed to be in pi form lol

Answer 22

haha okay so its 25pi?

Answer 23

yes

Answer 24

Find the area of a square with a diagonal of 8 cm.
A) 32 cm2
B) 18 cm2
C) 16 cm2
D) 12 cm2

Answer 25

the formula is 1/2d^2

Answer 26

so .5*8^2

Answer 27

32

Answer 28

What is the similarity ratio for two circles with areas 2pi m2 and 200pi m2?
A) 1:10
B)1:100
C)1:2
D)1:5

Answer 29

well, youd put 2:200. so simplify it. in this case, all you can do is divide by 2

Answer 30

what am i dividing by 2?

Answer 31

nvm its B, right?

Answer 32

yes

Answer 33

Find the area of the trapezoid.
A)307.5 in2
B) 365 in2
C) 615 in2
D)182.5 in2

Answer 34

\[\frac{ a+b }{ 2 }h\]

Answer 35

so \[\frac{ 20+29.2 }{ 2 }*12.5\]

Answer 36

307.5?

Answer 37

yep!

Answer 38

Find the area of the trapezoid
A) 307.5 in2
B) 365 in2
C) 615 in2
D)182.5 in2

Answer 39

@tylermcmullen23

Answer 40

we just done that one, remember? lol we got 307.5

Answer 41

oops my bad

Answer 42

its alright

Answer 43

Both trapezoids are similar. The area of the smaller trapezoid is 13 ft2. Which is the best approximation for the area of the larger trapezoid?
A) 20 ft2
B) 24 ft2
C) 28 ft2
D) 16 ft2

Answer 44

first, you wanna find the scale factor from the small to the large. to do this, divide 10 by 8

Answer 45

1.25

Answer 46

since the area for the smaller is 13, multiply it by 1.25

Answer 47

16.25

Answer 48

so your answer should be 16! :)

Answer 49

Both triangles are similar. The area of the smaller triangle is about 97 ft2. Which is the best approximation for the area of the larger triangle?
114 ft2
400 ft2
190 ft2
133 ft2

Answer 50

135.8

Answer 51

in this, i would say that 133 is your answer.. but im not entirely sure bc it didnt get as close as the trapezoid did.. thats weird

Answer 52

yolo

Answer 53

In circle P, PQ = 3 in. What is the circumference of the circle
36p in.
18p in.
6p in.
9p in.

Answer 54

since circumference is found by doind diameter*pi.. multiply 3 by 2 to get the diameter, which is 6, and multiply it by 3.14

Answer 55

18.84

Answer 56

again, its supposed to be in pi form.. ._.

Answer 57

so its just 18?

Answer 58

so its 6p

Answer 59

Thank you :-)

Answer 60

One circular table has a diameter of 9 ft, and another circular table has a diameter of 14 ft. How much greater is the area of the larger table? Round to the nearest whole number.
about 90 ft2
about 72 ft2
about 36 ft2
about 108 ft2

Answer 61

well, the area for the smaller table is solved by doing 4.5^2*pi
and for the larger, you solve by doing 7^2*pi

Answer 62

153.86?

Answer 63

yes that is correct for 7^2pi. but now, subtract 63.59from that

Answer 64

90.27?

Answer 65

Both trapezoids are similar. The area of the larger trapezoid is 61 ft2. Which is the best approximation for the area of the smaller trapezoid?
44 ft2
34 ft2
49 ft2
39 ft2

Answer 66

id say d..

Answer 67

Find the area of a regular hexagon whose apothem is 1.7 cm and side length is 2 cm.
3.4 cm2
10.2 cm2
20.4 cm2
6.8 cm2

Answer 68

first, do the formula for a triangle using the given info. so do 2*1.7*1/2

Answer 69

I got 1.7

Answer 70

ok now how many triangles make up a hexagon??

Answer 71

6?

Answer 72

yes. now multiply that by the number you got, 1.7

Answer 73

10.2

Answer 74

43°
37°
48°
24°

Answer 75

@tylermcmullen23

Answer 76

im not entirely sure... but maybe 37. just because its a little under 45, closest to what i thought the answer was
