\pi \left(36-12x+x^{2}\right)
Factor out \pi .
\left(x-6\right)^{2}
Consider 36-12x+x^{2}. Use the perfect square formula, a^{2}-2ab+b^{2}=\left(a-b\right)^{2}, where a=x and b=6.
\pi \left(x-6\right)^{2}
Rewrite the complete factored expression.
36\pi -12\pi x+\pi x^{2}
Multiply -1 and 12 to get -12.
