Answer:
Option C [tex]452\ cm^{3}[/tex]
Step-by-step explanation:
we know that
the volume of a cylinder (coffe cup) is equal to
[tex]V=\pi r^{2} h[/tex]
we have
[tex]r=8/2=4\ cm[/tex] -----> the radius is half the diameter
[tex]h=9\ cm[/tex]
substitute
[tex]V=\pi (4^{2})(9)=452.4\ cm^{3}[/tex]
Round to the nearest whole number
[tex]452.4\ cm^{3}=452\ cm^{3}[/tex]
