Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the volume of a cylinder is equal to pi * r^2 * h.

since your jar is in the shape of a cylinder, that's the formula that need to be applied.

since r = 3 cm and h = 8 cm, then the volume of a full jar is equal to pi * 3^2 * 8 = pi * 9 * 8 = 72 * pi cubic cm.

the jelly remaining in the jar has a height of 3 cm.

the volume of jelly remaining in the jar is equal to pi * 3^2 * 3 = pi * 9 * 3 = 27 * pi cubic cm.
