Question

Please, I am quite confused on how to get the volume of an irregular shape. I have been given basically 4 points ( origin - 0,3 - 3,0 - 4,3). If you connect the dots, you will get a shape that looks like a half reeses cup. Just using that shape, I am to find the volume of the candy (it's a candy) after it's been rotated about the y-axis.

Thank you for all your help!
In addition, I don't feel like the washer method would work here since it's a complete solid...
