Answer:

$222.312\:\mathrm{in^3}$

Explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone:
$(1)/(3)\cdot 2^2\cdot 3.14\cdot 8.1 =33.912$

Volume of the cylinder:
$2^2\cdot 3.14 \cdot 15=188.4$

Thus, the total volume of the solid is:

$33.912+188.4=\boxed{222.312\:\mathrm{in^3}}$
