Question

Help with math for a MEDAL!!!!!!!
The volume of a cone is three hundred cubic kilometers. If the radius of the base is 5 kilometers, what is the height of the cone? Use three point one four for pi. Show your work and round to the nearest tenth.

Answer 1

please dumb down your answer as much as possible, im terrible at this stuff

Answer 2

someone please help?

Answer 3

\[V= \frac{ \pi r^{2} h }{ 3 }\]
r= 5
V= 300
Can you plug it in and solve?

Answer 4

no can you please write it with words so i understand, im not good with symbols

Answer 5

volume = ( pi times (r square) times h ) / 3

Answer 6

h= height
r= radius
pi = 3.14

Answer 7

well explain what i do step by step in words please

Answer 8

ok first you put volume = 300 to this equation:
volume = ( pi times (r square) times h ) / 3

what do you get?

Answer 9

replace volume with 300

Answer 10

would it be 300=(pi) times (r square) times H) /3

Answer 11

yes now you put r = 5 into this equation :
300=(pi) times (r square) times H) /3
what do you get?

Answer 12

300=(pi) times (r 5) times H) /3

Answer 13

no, it's
would it be 300=(pi) times (5 square) times H) /3

Answer 14

now pi = 3.14 so replace pi with 3.14 in this equation:
300=(pi) times (5 square) times H) /3

Answer 15

ok well do i put 300=(pi) times (5 square) times H) /3 first on my exam or what?

Answer 16

is the exam asking you to show work?

Answer 17

yes

Answer 18

then first, put down the equation
\[V= \frac{ \pi r^{2} h }{ 3 }\]
then write that the equation you just brought up down.

Answer 19

well just show me how to write the whole thing, like how would i type it?

Answer 20

you still there?

Answer 21

do you know how to type these symbols?
V= (pi r^2 (h)) / 3

Answer 22

yes but are you sure this is right? i just want the answer typed out in words, no symbols like "Pi 2 r gjnjihjtrienjtyh+ + = 1/3 69" I want it typed out in words, the process of how to do this

Answer 23

like i want you to be like "than you multiply this and that divide this"

Answer 24

u there?

Answer 25

anyone there?

Answer 26

hello?

Answer 27

can someone just give me the answer without symbols and all this confusing stuff? can someone write it out in WORDS you will get a medal!

Answer 28

HELP!!!!

Answer 29

@study100

Answer 30

\[V= \frac{ pir^{2}h }{ 3 }\]
\[300 = \frac{ \pi (25) h }{ 3 }\]
\[\frac{ 300(3) }{ 25 \pi } = h\]
\[h= \frac{ 36 }{ \pi } = 11. 46\]

Answer 31

but you need to know how to do this on your own. Getting the right answer is not as important as understasnding how to do this.

Answer 32

i know, what im asking for you to do is explain this to me in words not symbols

Answer 33

say stuff like "then you multiply this then that, add that, subtract that"

Answer 34

@study100

Answer 35

@study100 r u there?

Answer 36

or can you only explain in symbols, is it not possible to write it in words, if it is, i understand but from the equations you are shwoing me, i dont know if im suppose to multiply something or divide something

Answer 37

volume = pi r squared times h all over 3
three hundred = thee point four times twenty five times h all over three
three hundred times three = three point four times twenty five times h

Answer 38

now you divide three point four to both sides

Answer 39

ok now that makes less sense just explain to me with symbols and words like show me the "3/4/69 8 5 pi r s ZZZ" stuff and explain to me what to do, because i just want to get this questions done, i want to know this! please

Answer 40

@study100

Answer 41

ok first of all, do you know how to plug in formulas?

Answer 42

do you know the area of the circle?
3. do you know what pi is?

Answer 43

do you know about radius/diameter/ volume of a cone? What makes up a cone?

Answer 44

pi is 3.14

Answer 45

ok good, what is the formula for area of circle?

Answer 46

i dont know

Answer 47

isnt it 1/3

Answer 48

no you've got a long a way to go.
Let's start with basics first, how many degrees is in a circle?

Answer 49

idk cant you just literally write the answer, im never gonna use this in life, you can have symbols just in between symbols and all that stuff write "and then i did" or something
