So it's going to be equal to pi times the integral from 0 to 2 of x to the fourth dx. I don't like that color. Now the antiderivative of x to the fourth is x to the fifth over 5. So this is going to be equal to pi times x to the fifth over 5. And we're going to go from 0 to 2. So this is going to be equal to pi times, this thing evaluated at 2. Let's see, 2 to the third is 8, 2 to the fourth is 16, 2 to the fifth is, let me actually just write it down, 2 to the fifth over 5 minus 0 to the fifth over 5.
