Sphere 1 has surface area A1 and volume V1 and sphere 2 has surface area A2 and volume V2. If the radius of sphere 2 is 3.53 times the radius of sphere 1, what is the ratio of the areas A2/A1 ?

1.25×101 & 4.40×101 are correct answers but i dont remember how i got them

  • physics -

    the ratio of the areas is the square of the ratio of the radii
