Find an equation of the largest sphere with center (2,9,3) that is contained completely in the first octant.

OpenStudy (amistre64):

the closest you are away from any given axis is 2

OpenStudy (anonymous):

so my radius would be 2^2?

sonofa can u help? would the volume b squared or cubed or just 24?

OpenStudy (anonymous):

so i can use (x-a)^2 + (y-b)^2 + (z-c)^2 = r^2 to get the equation?

OpenStudy (anonymous):

shanny inches x inches x inches is inches cubed

OpenStudy (amistre64):

yes, with a,b,c being the center points

OpenStudy (amistre64):

and r = 2

OpenStudy (anonymous):

kk thanks sonofa :D

OpenStudy (anonymous):

how do you gather the radius can only be 2 away at themost? is that just an analytical though?

OpenStudy (amistre64):

the first quadrant is bounded by the xyz axises; any thing that goes beyong those bounds is out of bounds

OpenStudy (amistre64):

since you closes distance to any given axis is "2"; your radius has to be confined to "2"

OpenStudy (anonymous):

alright..thx so much for your help and time

OpenStudy (amistre64):

youre welcome
