2. The area of a circle is calculated by multiplying the irrational number squareinches
That is highlight%2878.54%29squareinches when rounded to 2 decimal places.

3. The area of the wood piece left over, in square inches, is
300-78.54=221.46. The amount of wood left over after cutting out the circle is highlight%28221.46%29squareinches
