    Calculate the area of the region bounded by the curve y=root (9-x) and the coordinate axes in the first quadrant.

    Q1. The question is Sketch the curve x^2=4ay and shade the region bounded by the curve and the latus rectum y=a. Find the volume of the solid generated when this region is rotated about the axis of symmetry of the parabola.

    Q2. A sphere of radius r is generated by rotating the semi circle y = root (9-x). Calculate the area of the region bounded by the curve and the coordinate axes in the first quadrant and calculate the volume of the solid generated when the region is rotated about the x axis and the y axis.
