The answer is:  [C]:  61.38 cm  .
_______________________________________________

Note:  A = \(\pi *r\)²

300 = (3.14) r² ;
______________________
Divide each side by "3.14" ;

r² = 300/3.14 ; 

r² =  95.5414012738853503 ;

√r² = √(95.5414012738853503) ;

r = 9.7745281867661188048

Circumference, "C" = \(\pi\) d ;  (d = diameter = 2r);
 
C = 2\(\pi\)r ;

C = 2(3.14)*(9.7745281867661188048)

C = 61.384037012891226094144 ; which rounds to answer choice: 
                                                             [C]:  61.38 cm  .
