     The circumference of a circle is 272.68 m.     

     What is the approximate area of the​ circle?     

     Use 3.14 for pi .     

 

     272.68 m / 3.14 = 86.84 m  (diameter)     

                                  86.84 m / 2 = 43.42 m  (radius)

 

     Area  =  π r²  =  (3.14) • (43.42 m)²  =  5920 m²  (rounded)     

 

     Explain how the area of a circle changes when     

     the circumference of a circle changes.     

 

     When the circumference of a circle gets larger, that     

     means the circle got larger, and, as a consequence,     

     its area got larger.  The opposite happens when the     

     circumference gets smaller.
