Explanation:

Step1: Identify the solid shape

Rotating rectangle about side CD forms a cylinder.

Step2: Determine cylinder dimensions

Radius \( r = 6 \), height \( h = 8 \).

Step3: Calculate volume

Volume formula: \( V = \pi r^2 h \)
Substitute values: \( V = \pi \times 6^2 \times 8 = 288\pi \approx 301.6 \)

Answer:

301.6
