Cory is lining the top of a table with clear plastic. The table has a circumference of 4.71 feet. How many square feet of plastic will he need to cover the tabletop? Use 3.14 for π and round to the nearest tenth.

Solve  for the radius

 

4.71  = 2 (3.14)  *  r

 

r =   4.71  /   ( 2 * 3.14)  =  .75 ft

 

Plastic needed    =   (3.14)  (.75)^2   =    1.8  sq ft
