Best ResponseYou've already chosen the best response.1the 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=\[6.75 \pi\]

Best ResponseYou've already chosen the best response.1ok. so you have the equation for Circumference right, but you solved for the radius. Hint: What relationship exists between the diameter and the radius?

Best ResponseYou've already chosen the best response.0Well the are uses radius so thats why I solved for radius first

Best ResponseYou've already chosen the best response.1ok. so what information did the picture contain?

Best ResponseYou've already chosen the best response.1ok good. now how could you write the radius in terms of the diameter?

Best ResponseYou've already chosen the best response.1ok just let me know your final answer and I will tell you if it is correct

Best ResponseYou've already chosen the best response.1Although that is a correct answer it is usually better form to leave the answer in terms of pi because it is more accurate
