Use the Shell Method to find the volume of the solid obtained by rotating the region \( A \) in the figure about \( x=-3 \). Assume \( b=2, a=10 \). (Use symbolic notation and fractions where needed.) Find the volume of a solid obtained by rotating the region under the graph of the function \( f(x)=\frac{1}{x^{2}} \) about the \( x \)-axis over the interval \( [2,5] \). (Use symbolic notation and fractions where needed.)
