b.

$V=2\pi \int_a^b p\left(x\right)h\left(x\right)dx$

\begin{aligned} V&=2\pi \int_a^b p\left(x\right)h\left(x\right)dx && \text{Apply Shell method.} \\ &=2\pi \int_2^6 x\sqrt[3]{\left(x-2\right)^2\left(x-6\right)^2} dx && \text{Substitute} \ x \ \text{for} \ p\left(x\right) \ \text{and} \\ &\text{} && \sqrt[3]{\left(x-2\right)^2\left(x-6\right)^2} \ \text{for} \ h\left(x\right). \\ &\approx 2\pi \cdot 29.82 && \text{Use the IntegralCalculator.} \\ &\approx 187.25 \end{aligned}
