Question

a spherical fish bowl has a radius of 21cm. how many ml of water is needed to fill half the bowl?

Answer 1

volume of sphere given by formula
\[\frac{ 4 }{ 3 } *\pi* r^{3}\]

Answer 2

to fill half just half the value you get from formula

Answer 3

a spherical fish bowl has a radius of 21cm. how many ml of water is needed to fill half the bowl?

Answer 4

for full and for half devide by 2

Answer 5

=(1/2 )*(4/3)*pi* (0.21 m )^3

Answer 6

after calculation convert volume in ml

Answer 7

not quite
to fill the bowl you need 2/3 πr^3 cc's

Answer 8

thats 2/3pi*r^3

Answer 9

for full and for half devide by 2 right

Answer 10

no not quite. If the height of the water level is half the radius of the bowl then the volume is 5/24*pi*r^3

Answer 11

alekos u feel sleepy

Answer 12

V = (pi*h^2)(3r-h)/3

Answer 13

that is a sphere ...

Answer 14

half fill means u have to fill half oh the sphere that is half volume of the sphere to be filled

Answer 15

No a fish bowl is half a sphere

Answer 16

read the Q it is spherical
nothing is said about its base

Answer 17

so we will consider it like a ball

Answer 18

It says " a spherical fish bowl" not a "sphere"

Answer 19

ok i git it

Answer 20

mirzah. have they given you an answer?

Answer 21

okkk how u will find the height

Answer 22

i'm assuming that the height is half the radius because it says "half fill the bowl"

Answer 23

hahahahaha...that means it is full sphere lolllllllll

Answer 24

no it aint

Answer 25

than how u can consider h=r/2

Answer 26

for ur kind info bowl will be flat at base ...so not complete sphere and mouth will also open

Answer 27

because it says "half fill the bowl" which I'm assuming to be a hemi-spherical bowl

Answer 28

doesn't say bowl with flat base

Answer 29

THAN WHAT I SAID IN START

Answer 30

THAT WE HAVE TO CONSIDER IT AS SPHEREICAL

Answer 31

all depends on how you interpret the question

i say tomaato and you say tomayto
