The surface area of a sphere is found using the formula 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. What is the ratio of the surface area of the sphere to the surface area of the cube?

Respuesta :

surface areasphere=4pir^2

surface area cube=6pis^2 where s is the side
the side is 2r
SAcube=6pi(2r)^2=6pi4r^2=24pir^2

so sphere to cube is
4pir^2:24pir^2
divide both sides by 4pir^2
1:6
the ratio is1:6
