Answer:
The volume of a cone is given by the formula V=\frac{1}{3} \pi r^{2} hV=
3
1
πr
2
h
If we plug in the known information into the formula, we will get the answer.
d=2.75 ind=2.75in
We know radius is half of d, so r=0.5*2.75=1.375 inr=0.5∗2.75=1.375in
The height is given as 4 in.
Pluggin all of these in the original formula gives us:
V=\frac{1}{3} \pi (1.375)^{2} (4)=7.919 cubic inchesV=

(4)=7.919cubicinches
Rounded to the nearest tenth, our final answer is:
V=7.9 cubic inches
