proper way to sudo over ssh

Question

I have a script which runs another script via SSH on a remote server using sudo. However, when I type the password, it shows up on the terminal. (Otherwise it works fine)

Answer 1

echo $VAR_REMOTEROOTPASS | ssh -tt -i $PATH_TO_KEY/id_mykey $VAR_REMOTEUSER@$varRemoteHost 
echo \"$varCommand\" | sudo bash
