A 42" diameter table needs a tablecloth that hangs off the edge 8". What is the radius of the tablecloth?

Respuesta :

The initial diameter of the table is 42", but this diameter is to be extended by 8" (right and left), So the tablecloth  will have a diameter of 42+8+8 = 58"
and the radius of the tablecloth = 24"
