Question

bemoseemo · Answer

what kind of equation? if you need an equation for the circumference the answer would be $$\pi*r ^{2}$$

bemoseemo · Answer

but based on your information, do you need the equation for the location of the verticies or...

Im not sure thats all the question says

gabby_taylor1224 · Answer

I would probably assume the circumference

bemoseemo · Answer

here ya go x2 + y2 - 4x + 8y - 16 = 0 yeesh that took a while

gabby_taylor1224 · Answer

so would it be 3.14 X R ^2 
what would be my radius?

gabby_taylor1224 · Answer

so x2 + y2 - 4x + 8y - 16 = 0 would be my answer?

bemoseemo · Answer

yes
