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.

We need to find the area of the table top

 

The radius of the table top can  be found as

 

4.71 / ( 2*3.14) =  .75 ft

 

The area =  3.14 (.75)^2   = 1.776 sq ft  = 1.8  sq ft
