(20 pt) Carefully show all work and write your answers in the designated area. Consider a solid sonic boom, as shown below. It's outer shell can be described in 3-space as a cone: aty - (2+5)=0. -55255 (a) Using cylindrical coordinates, define the boom B as a region in (r, 0, =) space: B = (b) Find the integral that gives the volume of the boom B. Warning: an integral gives 'signed' volume, which is not what is asked. Splitting the integral into the parts above and below the r - y axis is required. Volume(B) =
