Answer:
[tex]47.1 inch^3[/tex]
Step-by-step explanation:
given
Diameter 3 inches
height of cone 2 inches
height of cylinder 6 inches
so the radius is [tex]r=D/2=3inches/2=1.5 inches[/tex]
volume for cylinder is:
[tex]V=\pi r^2h[/tex]
[tex]V= (3.14)(1.5)^2(6)[/tex]
[tex]V= 42.39 inch^3[/tex]
volume for cone is :
[tex]V=1/3 \pi r^2h[/tex]
[tex]V= 1/3(3.14)(1.5)^2(2)[/tex]
[tex]V=4.71 inch^3[/tex]
so the total volume of the bird feeder would be:
adding both volumes we get the answer
[tex]V= 42.39+4.71\\V= 47.1 inch^3[/tex]
