## anonymous 5 years ago Find the area of the solid obtained by rotating the region bounded by the given curves about the specified line. y=2-.5x, y=0, x=1, x=2, about the x-axis

use $\pi \int\limits_{1}^{2} y ^{2} dx$ or in your question $\pi \int\limits_{1}^{2} (2 - 0.5x)^2 dx$ before integrating expand the quadratic and then integrate $\pi \int\limits_{1}^{2} 4 - 2x + 1/4 x^2 dx$
