Given:

diameter = 40 mm

Formula:

V = ⁴⁄₃πr³

If π = 3.14, then find the following:

V = ?

r = ?

First, let's calculate radius using this formula: Diameter = 2 * Radius.

r = 40 mm/2

r = 20 mm

Then, we can get volume.

V = ⁴⁄₃ (3.14) (20) ³

V = ⁴⁄₃ (3.14) (8000)

V = 4 (25, 120) / 3

V = 100, 480 / 3

V = 33, 493 mm³
