Can you check my work and see if I did the problem correctly? Thanks!
A solid with a base formed by intersecting sine and cosine curves and built up with semi-circular cross-sections perpendicular to the x-axis. Find the area of the base and the volume of the solid.
Integral (-2.356 to .785) (sinx-cosx) dx =-2.828
½ pi Integral (-2.356 to .785) (.5(sinx-cosx))^2 dx = 1.234
