A drinking glass is shaped like a cylinder with a height of 12 cm and a radius of 4 cm. Maeva adds 25 spherical pieces of ice to the glass. The pieces of ice each have a diameter of 3 cm. How many cubic centimeters of water can Maeva add to fill the glass to the rim? Use 3.14 to approximate pi and express your answer in hundredths. ___cm3

volume of cylinder = volume of 25 spheres = 25 time the volume of 1 sphere = volume of cylinder -volume of spheres = volume not occupied by solid
Huh?
to express in hundredths means to 2 decimal places
So how would i find the answer?
start by actually reading my response
let me know what specific question you have
Uhh I believe I actually did...
so where did you get stuck let me try to clear it up for you
I dont know what to do to find the answer
do you know how to find the volume of a cylinder?
No
do you know how to find the volume of a sphere?
No
well do you understand my response now?
No
my response said find the volume of the cylinder and subtract the volume occupied by the sphere and te difference will be the space occupied by the water.
the volume of a cylinder = pi* r^2* h r is the radius and h is the height
volume of a sphere is 4/3*pi*r^3
the diameter is 2 times the radius so the radius of the sphere is diameter/ 2
do you think you can substitute the numbers and do the calculation now?
Ill try...
wow that's better!!
are you going to post? i have to leave soon
I dunno got nothing
