Evaluate the indefinite integral first.

$$\int \pi ^{2}\mathrm{d}x$$

Find the integral of \pi ^{2} using the table of common integrals rule \int a\mathrm{d}x=ax.

$$\pi ^{2}x$$

The definite integral is the antiderivative of the expression evaluated at the upper limit of integration minus the antiderivative evaluated at the lower limit of integration.

$$\pi ^{2}\times 2^{\frac{1}{2}}-\pi ^{2}\times 0$$
