Answer:

V=122.5in^3

Explanation:

The volume of a right circular cone can be found with the formula
$V=\pi r^2(h)/(3)$ .

So, just plug in the values that are given (by the way, the radius is found by dividing the diameter by 2 since it's half the value of the diameter).

$V=\pi r^2(h)/(3)\\V=\pi (3.8)^2((8.1)/(3) )\\V=\pi (14.44)(2.7)\\V=122.484\\V=122.5in^3$
