Question

The figure is made up of a cone and a cylinder.

Answer 1

Answer: $38\ mm^3$

Step-by-step explanation:

The figure is attached.

The formula to find the volume of the cone is:

$V=\frac{1}{3}\pi r^2 h$

Where "r" is the radius and "h" is the height of the height of the cone.

The formula for calculate the volume of a cylinder is:

$V=\pi r^2h$

 Where "r" is the radius and "h" is the height.

The volume of the figure is the sum of the volume of the cylinder and the volume of the cone.

Therefore, you get the following result (Using $\pi =3.14$)

$V_t=\frac{1}{3}(3.14) (2\ mm)^2 (3\ mm)+(3.14) (2\ mm)^2 (2\ mm)\\\\V_t=37.68\ mm^3\\\\V_t\approx38\ mm^3$
