(2)Find the volume of the torus which was formed by region the circular region bounded by (x-2)2 + y2 = 1about the y-axis.

5. The tangent line to the curve y = x3 at the point A(1,1) intersects the curve at another point B. Let R be the area of the region bounded by the curve and the tangent line. The tangent line at B intersects the curve at another point C. Let S be the area of the region bounded by the curve and the second tangent line. Find the values of R and S.
