c)602.88 ft3
d)1,406.72 ft3

Answer 1

LOL PLAY I MEN PLZ

Answer 2

Find the surface area of the object for number one.

Answer 3

Find the volume of the barrel for number two.

Answer 4

OK

Answer 5

AND

Answer 6

HELLLLOOOO

Answer 7

Hi, give me a sec to get the right formulas. brb

Answer 8

OK

Answer 9

#2 is V = (pi)(r^2)(h)

V = (3.14)(4^2)(7)
V = (3.14)(16)(7)
V = (351.68)(3)
V = 1055.04

The answer is A

Answer 10

OK

Answer 11

#1 is 2lw + 2lh + 2wh

l = 12
w = 8
h = 2


2(12)(8)+2(12)(2)+2(8)(2)
2(96)+2(24)+2(16)
192+48+32
272

The answer is A also.

Answer 12

WOW THX

Answer 13

NP

Answer 14

ONE MORE PLZZZ

Answer 15

Find the volume of a triangular prism with the following dimensions. Round to the nearest whole number.

triangle base: 5 ft
triangle height: 3 ft
prism height: 7.5 ft (1 point)
a)56 ft3
b)19 ft3
c)113 ft3
D)8 ft3

Answer 16

ok,give me a sec though

Answer 17

OK TYT

Answer 18

Working on it now…

Answer 19

OK

Answer 20

V = Area of base x height
A = 1/2 (b)(h1)
A = ½(5)(3)
A = ½(15)
A = 7.5
V = (7.5)(7.5)
V = 56.25
V = 56 (rounded)

The answer is A... I see a pattern

Answer 21

WOW YOUR GOOD

Answer 22

thx

Answer 23

That it?

Answer 24

NOT REALLY BUT YOU DONT HAVE TO HELP IF YOU DONT WHAT TO

Answer 25

umm.... fan me an' I'll do 1 more

Answer 26

OK

Answer 27

20. When baking a cake, you have a choice of the following pans:

a round cake pan that is 2 inches deep and has a 7 inch diameter
a 6 inch × 9 inch rectangular cake pan that is 2 inches deep
a. Which of these pans has the larger volume? Justify your answer.

b. How much icing will be needed to frost each cake, excluding the bottom of the cake? Justify your answer.

Answer 28

essay huh? ok, give me a sec

Answer 29

OK

Answer 30

A. Pan #1 is a cylinder, Pan #2 is a rectangular prism.
Pan #1: V = (3.14)(r^2)(h)
V = (3.14)(3.5^2)(2)
V = (3.14)(12.25)(2)
V = 76.93 in^3
V = 77 in^3 (rounded)

Pan #2: V = (l)(w)(h)
V = (6)(9)(2)
V = (6)(18)
V = 108 in^3

Pan #2 has a higher volume.
Gimme a sec for part 2.

Answer 31

OK

Answer 32

YOU THEIR

Answer 33

yeah

Answer 34

OK

Answer 35

Part 2 is a surface area minus a face. Just calculate the area of the face and set it aside. Calculate the surface area of that shape and subtract the area of the face.
#1: Area of a circle is: A = (pi)(r^2)
A = (3.14)(3.5^2)
A = (3.14)(12.25)
A = 38.47

Surface area of a cylinder: SA = 2 pi r 2 + 2 pi r h
2(3.14)(3.5^2) + 2(3.14)(3.5)(2)
2(3.14)(12.25) + 2(3.14)(3.5)(2)
2(38.47) + 2(22)
77 + 44
121
121-38.47 = 82.53
82.53 needs to be frosted for the first pan.

Area of a rectangle: A = (l)(w)
A = (6)(9)
A = 54

Surface area of a rectangular prism: SA = 2(a)(b) + 2(b)(c) + 2(a)(c)
2(6)(2) + 2(6)(9) + 2(2)(9)
2(12) + 2(54) + 2(18)
24 + 108 + 36
50 + 108
158

158 – 54 = 104
104 inches needs to be frosted.

That should do it. Sorry it took so long.

Answer 36

IT OK THXS

Answer 37

Free internet school help... good idea

Answer 38

LOL YA

Answer 39

Can the numbers 24, 32, 40 be the lengths of the three sides of a right triangle? Explain why or why not. PLZZZ HELPPPP

Answer 40

hmmm.... another essay? I'll try!

Answer 41

OMG OK

Answer 42

A^2+B^2 = C^2
24^2+32^2 = 40^2
576+1024 = 1600
1600 = 1600

Yes the side lengths can be from a right triangle. Using the Pythagorean Theorem the squares of two sides equal the square of the hypotenuse.


You or your sis do FLVS? I think I remember these questions from when I did it.

Answer 43

NO
