Given:

The radius of the cone is 2 cm.

The height of the cone is 2.25 cm.

We need to determine the volume of the cone.

Volume of the cone:

The volume of the cone can be determined using the formula,

$V=(1)/(3) \pi r^2h$

where r is the radius and h is the height of the cone.

Substituting r = 2 and h = 2.25, we get;

V=(1)/(3) (3.14)(2)^2(2.25)

Simplifying, we get;

V=(1)/(3) (3.14)(4)(2.25)

Multiplying, we get;

V=(1)/(3) (28.26)

Dividing, we get;

$V=9.42 \ cm^3$

Thus, the volume of the cone is 9.42 cubic cm.

Hence, Option b is the correct answer.
