Provide an appropriate response.The first-quadrant region bounded by y = 
, the x-axis, and the y-axis is revolved about the y-axis to form a solid. Explain how you could use elementary geometry formulas to verify the volume of the solid.
What will be an ideal response?
The resulting solid is a hemisphere of radius 2. The volume is given by V = 
?r3 = 
?
