Question

@hartnn Could you please help me with this question?

Answer 1

Is it asking for the volume of a cylinder?

Answer 2

it is asking for volume of cylinder - volume of 9 marbles

Answer 3

that will be the volume of water

Answer 4

Do I calculate the volume of this cylinder?

Answer 5

\(\pi R^2 h - 9\times (4/3)\pi r^3\)

R = 6/2
r =2/2
h=12

Answer 6

yes

Answer 7

but there are two radius' ... :/

Answer 8

find volume of cylinder (pi R^2 h)
volume of marbles also (4/3 pir^3 )

Answer 9

one radius is of Cylinder
thats R = 6/2 = 3

Answer 10

other one is for marbles
thats
r = 2/2 = 1

Answer 11

V of marbles= 37.7

V of Cylinder= 339.29

Answer 12

don't plug in value for pi
keep pi as pi only

Answer 13

if you subtract those volumes, you get volume of water

Answer 14

So I don't have to do it over again, I can just subtract the two volumes I have so far?

Answer 15

you will get the answer, but NOT in terms of pi
options are in terms of pi
