Aparallelogram is graphed on a coordinate plane so that two points are in the first quadrants and two points are in the third quadrant. what are possible coordinates of the vertices of the parallelogram?

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8
