Answer:

113.1 cubic inches

Explanation:

The volume of a cylinder is given by the formula:

$V=\pi r^2 h$

Where

V is the volume

r is the radius

h is the height

Given, h = 9 and r = 2, we substitute and find the volume:

$V=\pi r^2 h\\V=\pi (2)^2 (9)\\V=36\pi\\V=113.097$

We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:

113.1 cubic inches
