                                           Your answer should be:

                                                             66

                                                          Why...?

                                                         Simple.

       First, you multiply 21 by 22/7. But to make this easier you have to fix in       'improper fraction.' and make it into an improper fraction. Which will become   3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.

I hope this helped!!!
