A cylindrical vase has a radius of 3.2 cm. When filled to the very top, it holds 220.167 cubic centimeters of water. What is the height of the vase? Explain
or show your reasoning with a drawing and/or mathematical formula.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Can someone check if i did this correct. it’s number 4 if you’re wondering.
