Calculus (area of base and volume of solid)
posted by Anonymous .
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 semicircular crosssections perpendicular to the xaxis. Find the area of the base and the volume of the solid.
Integral (2.356 to .785) (sinxcosx) dx =2.828
½ pi Integral (2.356 to .785) (.5(sinxcosx))^2 dx = 1.234
