Answer:

4.4 cubic inches

Step-by-step explanation:

From the question;

  • Radius of the cone is 1.2 inches
  • Height of the cone is 2.9 inches

We are required to determine the volume of a cone;

Volume of a cone is given by the formula;

V=1/3πr²h

Therefore; taking π to be 3.142

Volume =1/3 × 3.142 × 1.2² × 2.9

             = 4.373664

             = 4.4 cubic inches (to the nearest tenth)

Thus, the volume of a cone is 4.4 cubic inches
