Question

:) help me pleasee..
A spherical storage tank has a diameter of 14 ft. How many cubic feet of water will it hold?
______ cubic ft.

Answer 1

The radius is half the diameter

Radius: r = d/2 = 14/2 = 7


So r = 7


Volume of a sphere:


V = (4/3)*pi*r^3


V = (4/3)*pi*(7)^3


V = (4/3)*pi*343


V = 343*(4/3)*pi


V = (1372/3)*pi


V = 457.33333*pi


V = 457.33333*(3.14159)


V = 1436.7538


So it will hold approximately 1436.7538 cubic ft of water.

Answer 2

i got that too but it says its wrong..

Answer 3

Use more digits of pi to get a more accurate answer (if necessary)

Answer 4

How many digits do they want you to round to?

Answer 5

it just says.. in the end (use \[\Pi =\] 22/7

Answer 6

so maybe put it in a fraction??

Answer 7

oh thanks for the clarification

Answer 8

and its just a box.. and you have to enter the digits so idk

Answer 9

V = (4/3)*pi*r^3


V = (4/3)*pi*(7)^3


V = (4/3)*pi*343


V = 343*(4/3)*pi


V = (1372/3)*pi


V = (1372/3)*(22/7)


V = (1372*22)/(3*7)


V = 30184/21


V = 4312/3


V = 1437.333


So the volume is approximately 1437.333

Answer 10

its not that either:l is there any way that you could put that as an improper fraction or so??

Answer 11

Did you try the answer 4312/3 ?

Answer 12

no.. ill try it hold on.. :)

Answer 13

YESS ITS CORRECT :D <3 thank youuu thank youu thank youu:)

Answer 14

You're welcome
