If a cylinder of radius 2 cm and height 4 cm is submerged in a graduated cylinder of radius 3 cm containing a liquid. By how much does the liquid rise?

Given:

Cylinder = radius 2cm; height 4cm

graduated cylinder = radius 3cm w / liquid

Volume of a cylinder = π r² h = 3.14 * (2cm) ² * 4cm = 50.24 cm³

Volume of a cylinder = Volume of the graduated cylinder

50.24 cm³ = 3.14 * (3cm) ² * h

50.24 cm³ = 28.26 cm² * h

50.24 cm³ / 28.26 cm² = h

1.78 cm = h

The liquid rises by 1.78 cm in the graduated cylinder.
