8. Hannah approximates the areas of circles using the equation A = 3r1, and records areas of circles with different radius lengths in a table Radius (in 1 2 3 4 5 3 12 27 48 75 Area (in.) a. Graph the ordered pairs from the table. b. Is the relation a function? Explain.

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 is c
