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

Sorry its sloppy but does that look right so far?

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

just the picture and to use 3.14

ok. so what information did the picture contain?
 one year ago

FibonacciChick666Best ResponseYou've already chosen the best response.1
ok good. now how could you write the radius in terms of the diameter?

well its half the diameter

so do we have the information we need to answer the question?

Actually I think I figured it out I got what I was doing wrong now

ok just let me know your final answer and I will tell you if it is correct
 one year ago

FibonacciChick666Best ResponseYou've already chosen the best response.1
Although that is a correct answer it is usually better form to leave the answer in terms of pi because it is more accurate

dependent upon your teacher though
