The average arm span of a group 10 first graders is 47 inches.if they hold hands and stretch to form a circle what will the approximate diameter of the circle

Question

Please include equation and make sure all numbers are correct and on point

Answer 1

   (47 inches)/(person) * (10 persons) = 470 inches             [persons cancel]

 

     for a circle, Circumference = Π*(diameter)

 

  So,

    (diameter) = (Circumference) / Π

    (diameter) = 470 / Π  inches

 

You may use 3.14 or 22/7 to approximate Π.  You may also convert the inches to feet and inches.
