your gonna have to send a pic i think
haha! Yeah, It's kind of hard to explain. I can type in the complete problem on the sheet but I don;t have a scanner.
use 'paint' on your computer...if you got windows that is
ahh...okay, one moment...
Okay, the circle on the bottom is the one that needs to be circumscribed and tangent to the other one on the outter side.
I know the standard formulas for the two circles here but I need the standard fromuls for the circle that circumscribes the bottom circle and is tangent to the top
kinda like this?
whats equations of your circles then
you mention triangles, care to ellaborate?
well....not exactly triengles. The tengents of a circle....the line that intersects it at only one point. Top circle is....81=(x+4)^)squared)+(y-1)^squared bottom= 64=(x+2)squared+(y+4)squared
I'm so lost!
lets equate these 2 and see where they intersect
but they overlap, no?
if there is a solution to equating them then yes...so lets check it :)
if i did it right; they overlap at the line 4x-10y=20.... and that is providing i didnt mess it up lol
i have the answer and it says the equation is 484=(x+2)squared+ (y+4)squared
heres your 2 circles plotted on the graph
if what you told me is right; then the new equation should equal between 196 and 225
