{3 + i, 3 - i, 3, -1}

step-by-step explanation:

the answer is 99.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
