No. The tape you have is of a radio program, but it is not a recording made under Part VA for educational purposes, and thus may not be copied under Part VA.

You can play the tape in class.

If you missed a radio broadcast, you might want to see if Screenrights can put you in touch with another educational institution which may have copied the program under Part VA. Alternatively, contact the radio station to see if it can sell you more copies or give you permission to make the copies you need.
