Answer 1

C=2*pi*r
66=44r/7
66*7/44=r
10.5=r

the radius is 10.5m

Answer 2

==================  HEYA THERE ==========


------------------------  HERE IS YOUR ANSWER ----------------------



                                  ============

   $C = 2 * \pi * R$



66=44r
     ____
       7
                         = > 66*7/44=r




10.5=r

THEREFORE the radius is 10.5m
