Given: Diameter of the base of a cylinder is 4 cm.

Its height is 14 cm.

Volume of the Cylinder is given by: πr²h. (here r and h are radius and diameter respectively)

Let V be the volume of the cylinder.

∴ V = πr²h

⇒ V = π × ()² × 14 (∵ 4 is the diameter and is the radius)

⇒ V = π × (2)² × 14 = π × 4 × 14

⇒ V = 176 cm³

∴ The volume of the cylinder is 176 cm³
