Answer:

  154 in²

Step-by-step explanation:

The area of the cake top is given by the formula for the area of a circle.

  A = πr²

Here, it is convenient to use the approximation π ≈ 22/7, so we have ...

  A = (22/7)(7 in)² = 154 in²

The baker should use 154 square inches of frosting for the top of the cake.
