Can someone solve this problem with a=1 please

2. (20 points) Volume of revolution a. Sketch the region bounded by y = ax2, y = 0, and x = a. b. Draw a representative rectangle for find the volume of the object rotated around x = a using the disk method. c. Set up an integral to find the volume of the object using the disk method. Do not solve the integral, but do explain what each part of the integral represents geometrically. d. Resketch the region and draw a representative rectangle for find the volume of the object rotated around x = a using the shell method. e. Set up an integral to find the volume of the object using the shell method. Do not solve the integral, but do explain what each part of the integral represents geometrically. f. Choose one of the integrals to determine the volume of the object
