Dear Julie,

I think you can find the information that you are seeking on some of the Ask
Dr. Math pages. For example,

Circle Formulas
http://mathforum.com/dr.math/faq/formulas/faq.circle.html

Quadrilateral Formulas
http://mathforum.com/dr.math/faq/formulas/faq.quad.html#parallelogram

You can find more information about circles and/or parallelograms here:

Geometry
http://mathforum.org/dr.math/tocs/geometry.middle.html

http://mathforum.org/dr.math/tocs/geometry.high.html

Then if you search on http://google.com for "circles math" here are a few
sites:

Hoxie High School Mathematics Department: Circles
http://www.hoxie.org/math/geometry/circles.htm

Math Forum: Measurement: Circles
http://mathforum.org/paths/measurement/m.drmath.circ.html

...and here are some I found searching for "parallelogram math"
