1-Consider the curve f(x)=sqrt(25-x^2 )between x = 2 and x = 4. What is the volume obtained by revolving the curve around the x-axis?

2-Consider the area enclosed between the curves f(x)= (x^2)+1 and f(x)= 9-(x^2). What is the volume obtained by revolving the area between these two curves around the line y=-1?
