    the diameter of the circle is 3in. Why? the diameter is parallel to a side. So we will calculate the area of the circle and subtract that value from the area of the square. so area of the square=l*w=3*3=9 area of the circle=\[\pi \times r^{2}\]=\[\pi\times 3/2^{2}\]. THIS YIELDS: \[9- 9/4 \times \pi\] then put into a calculator and get A=\[6.75 \pi\]

    Do you think you could check a few others? Im not sure if I did them right

    ok. so you have the equation for Circumference right, but you solved for the radius. Hint: What relationship exists between the diameter and the radius?

    Well the are uses radius so thats why I solved for radius first

    ok good. now how could you write the radius in terms of the diameter?

    well its half the diameter

    Although that is a correct answer it is usually better form to leave the answer in terms of pi because it is more accurate
