Présentation de l'éditeur

The diameter of the bottom of this Petri dish is 3inches or 7.5 +centimeters. The area of a circle is equal to the square of the radius multiplied by or 227. i 12 in. =radius. 112x112=2.25. 2.25 x227 =7.07 square inches. 3.75 cm. =radius. 3.75x3.75 =14.06. 14.06 x227 =44.1 square centimeters. Number of bacterial colonies in i sq. in. averages, approximately, 75. Number in 7.07 sq. in. =530. Number of bacterial colonies in i sq. cm. averages, approximately, 12. Number in 44.1 sq. cm. =528. In a microscopic field, if the diameter were 8small squares (120 mm.), the radius would be 4small squares and the area of such a round field would be 4x 4= 16 x227 =50 +. Such a field would contain 50 small squares.
