my destrroyer #95 has a picture of cube that has a sphere in it. it gives us the cube side-length. and using that length, it wants us to find the length of sphere in it. However, the length of sphere is different from the length of cube in the picture. The sphere is not even touching the side of the cube. is this fixed in a new edition? edit: #101 is supposed be absolute value like the answer says. Instead, it has big brackets. also, the answer is E(that's what the answer says) but there is no choice E... is this fixed in a newer edition?
