Question

MEDAL! a circle has its center at (2 -4) and a radius of 6 units. what is the equation of the circle

Answer 1

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

Answer 2

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

Answer 3

Im not sure thats all the question says

Answer 4

I would probably assume the circumference

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

yes

Answer 9

my brain needs to rest after a long day of questions like these
