Intigration (volume of solids rotating about and axis)

[jkw0002]

the solid lies between planes perpendicular to the x-axis at x=1 and x=-1 the cross-sections perpendicular to the x-axis are

A) circles whose diameters stretch from the curve y = -1/squrt(1+x^2) to the curve y = 1/squrt(1+x^2)

B)vertical squares whose base edges run from the curve y = -1/squrt(1+x^2) to the curve y = 1/squrt(1+x^2)

A) circles whose diameters stretch from the curve y = -1/√(1+x²) to the curve y = 1√(1+x²)

B)vertical squares whose base edges run from the curve y = -1/√(1+x²) to the curve y = 1/√(1+x²)
