Answer:

  D.  480π cm²

Step-by-step explanation:

You want the area of a table 23 cm in radius that is not occupied by a dish that is 7 cm in radius.

Area

The area of each circle is given by ...

  A = πr²

The area of the table is ...

  A = π(23 cm)² = 529π cm²

The area of the dish is ...

  A = π(7 cm)² = 49π cm²

The area of the table not occupied by the dish is the difference:

  unoccupied area = (529π -49π) cm²

  unoccupied area = 480π cm² . . . . . . . . . matches choice D
