a.) (x + 1)2 + (y + 2)2 = 4
b.) (x - 1)2 + (y - 2)2 = 4
c.) (x - 1)2 + (y - 2)2 = 16
d.) (x + 1)2 + (y + 2)2 = 16

Find the volume of the solid whose base is the region bounded by f(x), g(x) and the x-axis on the interval [0, 1], and whose cross-sections perpendicular to the y-axis are squares. your work must show the integral, but you may use your calculator to evaluate it. give 3 decimal places for your answe
