geometry help

<p>hello guys, i am facing a slight problem.</p>

<p>I skipped the geometry course in school and jumped directly into ALG.2</p>

<p>so i can safely say that geometry is my main weakness in the math section. i can easily knock out the 1 thru 14 geo. questions, just afterwards it gets tricky. </p>

<p>for example finding the area of the regions of the shaded parts of a circle with a square inscribed inside it. i know that it is Acircle - Asquare = Ashaded regions but i cant seem to get the answer..</p>

<p>other example, area of a sector..</p>

<p>length of a radius of circle B in a "2 circles tangent to each other" problem</p>

<p>area of diagonal triangle inscribed in a cube</p>

<p>length of diagonal of cube going thru the center</p>

<p>problems like: if f(x) = blahblahblah then k(x)=? </p>

<p>i feel that if i nail all these types of problems, i would get a lot of free ppoints.</p>
