Answer: The approximate area of the circle is: 3,629.84 cm² .
______________________________________________________
Area of a circle, "A" : A = π * r² ;
in which: A = Area of circle ;
π ≈ 3.14 ;
r = radius;
radius of a circle, "r" = d / 2 ; in which: "d = diameter" ;
Given "d = 64 cm " ;
r = d / 2 = 64 cm / 2 = 32 cm ;
____________________________________________
So; A = π * r² ;
A ≈ (3.14) * (32 cm)² ;
A ≈ (3.14) * (1156 cm²) ;
_____________________________________________
A ≈ 3,629 .84 cm² .
