Describe three-dimensional solids formed by rotations and translations of plane figures through space. 1) Consider the rectangle that has a vertex at (0,0). Suppose you rotate the rectangle around the y-axis. a.) What is the name of solid formed by the rotation? Cylinder (0, 4) (3, 4) 1 b.) What is the volume of the solid formed by the H-4 (0, 0) (3. 0) 4 rotation? V= TTrah O a) How could you create this object with a 2.) Consider this three-dimensional object. rotation? Draw a picture and explain. O b) How could you create this object by stacking two-dimensional figures? Explain and draw a picture if needed. a cylinder perpindicold
