A cylindrical juice container has a volume of 1256 cu cm and raduis of 30 cm, how tall is the container

v = π r^2 h ... 1256 = π * 30^2 * h

check your numbers ... h seems VERY small

Vol = π r^2 h

1256= π(30)^2 h
h = 1256/(900π) = .444 cm

What a weird looking juice container.
Visualize a large pizza cooking plate with just tiny ridge around it.
Dare you not to spill it.
