a.x^4/4y^4
b.x^12/4^13
c.x^4/4
d.4x^4/y^4

Answer 1

as

Answer 2

hope that helps

Answer 3

that wasn't an option @katragaddasaichandra

Answer 4

it is B

Answer 5

okay thank u @katragaddasaichandra

Answer 6

The surface area of a sphere is found using the formula sa=4pier^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 24r^2 . What is the ratio of the surface area of the sphere to the surface area of the cube?

@katragaddasaichandra

Answer 7

well just equate the 2 surface areas and simplify
4πr2=24r2
simple as that

Answer 8

or perhaps
4πr2:24r2

Answer 9

but it looks like you are required to write the ratios as fractions so its
4πr224r2
