If a big cylinder has the radius of 24cm and a height of 18cm, what would the height be for the smaller cylinder with 4cm as the radius?
Thank you so much.

Is the volume of the small cylinder the same as the volume of the large cylinder. I think it must be; otherwise, I don't believe you can solve the problem.
Yes.
I've been at this since 3:00 and I'm getting nervous. I really need help.
volume of large cylinder = pi*r^2*h = 3.14(24)^2(18) = ? cc.
For the small cylinder
V = pi*r^2*h
?cc from above = 3.14(4)^2*h
Solve for volume of large cylinder, substitute that for volume of small cylinder and solve for h of small cylinder.
For the small cylinder
V = pi*r^2*h
?cc from above = 3.14(4)^2*h
Solve for volume of large cylinder, substitute that for volume of small cylinder and solve for h of small cylinder.
the answers are
A. 3cm
B. 6 cm
C. 9 cm
D. 18 cm
with a radius of 4 cm.
A. 3cm
B. 6 cm
C. 9 cm
D. 18 cm
with a radius of 4 cm.
None of those numbers fit. Do you have a picture of the cylinder? Is it a regular (right) cylinder or an ellipsoid cylinder. It must not be a right cylinder. Here is a picture of a right cylinder. You can google image cylinder and see what the ellipsoid one looks like.
