Angelawants to cover a footrest in the shape of a rectangular prism with cotton fabric. The footrest is 14 inches by 11 inches by 13 inches. She has 1 square yard of fabric. Can she completely cover the​ footrest? Explain

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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,
