A42" diameter table needs a tablecloth that hangs off the edge 8". what is the area of the tablecloth? use 3.14 for π.

The diameter of the table is 42 inches. The radius of the table is half of the diameter of the table, so the radius of the table is 42/2 = 21 inches. 

Add on 8 inches to the table radius to get: 21+8 = 29

So the radius of the table cloth is r = 29

Plug this into the area of a circle formula

A = pi*r^2
A = pi*29^2
A = pi*841
A = 841pi
A = 841*3.14
A = 2640.74

The approximate area of the table cloth is 2640.74 square inches.
