1)A cylindrical hole of radius "a" is bored through a solid right-circular cone of height "h" and base radius b>a.
   If the axis of the hole lies along that of the cone find the volume of the remaining part of the cone.



2)Find the
  (a)area
  (b)centre of mass

of the solid plate defind by the region in the xy-plane bounded by y=x^2, and y = x.
Assuming that the denstiy of the plate is proportional to the distance from the x-axis and the total mass of the region is M.
