1. You must apply the formula for calculate the volume of a cone and and the volume of a cylinder. Then, you must sum both volumes to obtain the volume on the figure attached.
2. Volume of the cone:
Vcone=1/3(πr²h)
π=3.14 r=4 mm/2 r=2 mm h=3 mm
3. When you substitute the values above into the formula, you obtain: <span> Vcone=1/3(πr²h) </span> Vcone=12.56 mm³
4. The volume of the cylinder is:
Vcylinder=<span>πr²h </span> π=3.14 r=4 mm/2=2 mm h=2 mm
5. <span>When you substitute the values above into the formula, you obtain: </span> Vcylinder=25.12 mm³
