Answer:

222.312\:\mathrm{in^3}

Step-by-step 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: \frac{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}}
