Question 585213
The surface area of one sphere is 144 times the area of another sphere. What is the relationship between the radii of the 2 spheres?
**
Formula for the surface of a sphere=4πr^2
Which means the surface area of a sphere varies as the square of the radius or conversely, the radius varies as the sqrt of the surface areas. In other words, the sphere with 144 times the area of another sphere will have a radius√144=12 times that of the other sphere.
