Question

The figure is made up of a cone and a cylinder. To the nearest whole number, what is the approximate volume of this figure? Use 3.14 to approximate π . Enter your answer in the box.


mm³

Answer 1

the complete question in the attached figure

we know that
[volume of a cone]=pi*r²*h/3
diameter=4 mm-------------> r=D/2----------> r=2mm
h=3 mm
so
[volume of a cone]=pi*2²*3/3--------> 12.56 mm³

[volume of a cylinder]=pi*r²*h
r=2mm
h=2 mm
[volume of a cylinder]=pi*2²*2--------> 25.12 mm³

[volume of a cone and a cylinder]=[volume of a cone]+[volume of a cylinder]
[volume of a cone and a cylinder]=[12.56]+[25.12]------> 37.68 mm³------> 38 mm³

the answer is
The volume of a cone and a cylinder is 38 mm³
