The surface area of a sphere is found using the formula sa=4pir^2 where r is the radius of the sphere. The surface area of a cube that is the same height and width (2r) as the sphere is 24pi^2 What is the ratio of the surface area of the sphere to the surface area of the cube?
Did you mistype the ratio part? Surface area to surface area will be 1 but I have a feeling that is not what you meant.

A- pi/6 B- pi/6r^4 C- pi/20 D- pir^4/6
well just equate the 2 surface areas and simplify \[4\pi r^2 = 24r^2\] simple as that
or perhaps \[4\pi r^2:24r^2\]
but it looks like you are required to write the ratios as fractions so its \[\frac{4\pi r^2}{24r^2}\]
