Question

can u define V=ttr^3/3

Answer 1

is this maths or physics

Answer 2

a city stores fresh water in a spherical tank. the tank has a radius of 32 feet. if they drain 140000 gal how much is left answer is 886763gal
volum+4tt r^3/3
V=4tt *32^3/3
V=137258.27743 cubic ft
1ft^3=7.48052gallons
7.48.52*137258.27743-140000=
886763 gallons

Answer 3

as the tank is spherical

u need to use the formula for volume of sphere.

Answer 4

\(\large \color{black}{\begin{align} V_{sphere}=\dfrac{4}{3}\pi r^3\\~\\
\end{align}}\)

Answer 5

here \(\large \color{black}{\begin{align} \pi=3.14\\~\\
r=radius
\end{align}}\)

Answer 6

so how do u do radius3

Answer 7

(radius)3

Answer 8

\(\large \color{black}{\begin{align}
r=radius=32^3=32\times 32\times 32=32768
\end{align}}\)

see if that makes sense

Answer 9

ok

Answer 10

so 32768x3.14x.75

Answer 11

no i mean1.33

Answer 12

so when tank is full total water will be

\(\large \color{black}{\begin{align} V_{sphere}& =\dfrac{4}{3}\pi r^3\\~\\
& =\dfrac{4}{3}\times 3.14\times32768\\~\\
& =1.33\times 3.14\times32768\\~\\
\end{align}}\)

Answer 13

136845.7216

Answer 14

http://www.wolframalpha.com/input/?i=%3D4%2F3times+%5Cpi+%5Ctimes32768%5C
so
\(\large \color{black}{\begin{align}
V_{sphere}=137258.2
\end{align}}\)

Answer 15

a small difference happens but its ok

Answer 16

how do i get 137258

Answer 17

use calculator

Answer 18

i did it keeps coming up 136

Answer 19

136845.7216

Answer 20

dont put 1.333 multiply with 4 and divide by 3 also use \(\Large \pi\) symbol instead of \(3.14\)

Answer 21

shall we proceed

Answer 22

i dont understand X with 4 and div by 3 i understand tt though could u show it

Answer 23

and what does ^ mean

Answer 24

value of \(4/3\) is not \(1.33\)

its \(1.3333333333333333333333333333333.................\)

so thats why we use that

see the link it is of calculator

http://www.wolframalpha.com/input/?i=%3D4%2F3times+%5Cpi+%5Ctimes32768%5C

Answer 25

no i have that i only put 1.33

Answer 26

see this

http://www.wolframalpha.com/input/?i=4%2F3%3D

Answer 27

my next answer is 1ft ^3= 7.48052 gal

Answer 28

yes

Answer 29

can u show the process 1ft^3

Answer 30

i dont know what ^ is

Answer 31

\(\large \color{black}{\begin{align}
V_{sphere}=137258.2 ~~cubic~~ feet
\end{align}}\)

we have to change it in gallon

\(\large \color{black}{\begin{align}
1~~cubic~~ft=7.48~~gallon
\end{align}}\)

so



\(\large \color{black}{\begin{align}
V_{sphere}=7.48\times 137258.2 ~~gallon
\end{align}}\)

Answer 32

my formulas sheet sorry i feel stupid right now

Answer 33

\(\large \color{black}{\begin{align}
V_{sphere}=7.48\times 137258.2=1026691 ~~gallon
\end{align}}\)

Answer 34

when 140000 gallon id drain , total water left is

\(\large \color{black}{\begin{align}
water~~left=1026691-140000=886691~~ gallon
\end{align}}\)

Answer 35

ok so my next one is an order of 12 balls packek for shipment each ball is 9 inches in dia and weighs 14 oz if the shipment is based on vol so dia is 9 so the r+4.5

Answer 36

thanks for ur help

Answer 37

so what does vol= 4/3 pi x r^3

Answer 38

ball is sized as sphere

so u will have to use sphere formula

Answer 39

1.33 x 3.14 x r^3 means 4.5x4.5x4.5 =380.556225

Answer 40

right

Answer 41

no only \(r^3=4.5^3=4.5\times 4.5\times 4.5\)

\(1.33 \times 3.14 \times r^3
\\=1.33 \times 3.14\times 4.5\times 4.5\times 4.5\)

Answer 42

I thougt thats what i just did i have 380 i dont have a pie botton

Answer 43

the answer is 382 i need the pie botton

Answer 44

if u dont have \(\pi \) use \(3.14\)

Answer 45

i did

Answer 46

by the way can u write ur complete question , it seems a little incomplete

Answer 47

ok

Answer 48

A farmer normally mixes 1 1/2 gallons of pesticide solution with 5 ... How much pesticide solution should the farmer place in a 350 ... show more ...

Answer 49

A farmer normally mixes 1 1/2 gallons of pesticide solution with 5 1/4 gallons of water for each acre of his fields.

How much pesticide solution should the farmer place in a 350 gallon tank in order to treat his 45 acre field?

Either
11.7 gallons
67.5
77.8 or
236.

I got 77.8.

1 cubic foot = 7.48 gal

Answer 50

i thought ur question is this one ?

ok so my next one is an order of 12 balls packek for shipment each ball is 9 inches in dia and weighs 14 oz if the shipment is based on vol so dia is 9 so the r+4.5

Answer 51

ok hold on and ill past it out

Answer 52

An order of 12 balls is being packed for shipment to New Jersey. Each ball is 9 inches in diameter and weighs 14 ounces. If the shipment charges are based on the volume of the balls, what is the volume of one of the balls? A) 85 cubic inches B) 286 C) 382 D) 3052

I am getting 381.5, not sure though I need this to be correct, thank you.

You need the following formula:

V = (4/3)(3.14)(r^3)

The diameter is 9 inches, which means the radius is 9/2.

Let V = volume

V = (4/3)(3.14)(9/2)^3

V = (4/3)(3.14)(81/4)

V = 84.78, which can be rounded off to the nearest unit to become 85 cubic inches.

Answer 53

i have 380 with this one its 382 on the paper i think becauce no TT

Answer 54

i just loked up my s4 and i can use pie know

Answer 55

\(\large (\frac{9}{2})^3=\frac{729}{8}\) not \(81/4\)

Answer 56

9/2 is 3x3x3 ?

Answer 57

27

Answer 58

\((\dfrac{9}{2})^3=\dfrac{9\times 9\times 9}{2\times 2\times 2}\)

Answer 59

ok i see

Answer 60

\(V = (4/3)(\pi)(9/2)^3 =381~~cubic~~inches\)

Answer 61

u rock i see

Answer 62

can we do one more

Answer 63

sry i have to go now but u can post more questions as u wish

and tag people for help like this @jon_1
