Volume of sphere is given as ![4 over 3 πr cubed](https://images.topperlearning.com/topper/tinymce/cache/a45f316527862586e99d0a3f8cdb9804.png)
![4 over 3 πr cubed](https://images.topperlearning.com/topper/tinymce/cache/a45f316527862586e99d0a3f8cdb9804.png)
Radius is 2r, so the volume will be ![equals 4 over 3 straight pi open parentheses 2 straight r close parentheses cubed equals 4 over 3 straight pi cross times 8 straight r cubed equals 32 over 3 πr cubed](https://images.topperlearning.com/topper/tinymce/cache/deb894185f0bb647d4ed6d855ab14e3f.png)
