A volume is described as follows: 1. the base is the region bounded by x = -y² + 8y + 52 and x = y² y²-22y + 140; 2. every cross section perpendicular to the y-axis is a semi- circle. Find the volume of this object.

Choose the correct awnser. Find the volume of the solid whose base is the region enclosed by the semi-circle y=(1-x^2)^1/2 and the x-axis, and whose cross-sections perpendicular to the x-axis, and whose cross-sections perpendicular to the x-axis are squares.  a) 3/2  b) 5/4  c) 6/5  d) 4/3  e) pi/2  f) 1

A volume is described as follows: 1. the base is the region bounded by x = – y² + 16y – 26 and x = y? – 26y + 182; 2. every cross section perpendicular to the y-axis is a semi-circle. Find the volume of this object. volume %3D
