/dev/sda3 10% /
According to your output the root directory is not part of your volume group but is a primary partition on your disk.
The only way to extend this, is when there is still unallocated space after this partition.
You can check this with the normal partition tools like fdisk.

NB: If you going to change partitions, always make sure you have a recent and valid backup.
