Algebra.Com's Answer #750201 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "It is not necessary to use the formula for the surface area of a sphere to answer this question. \n" ); document.write( "All spheres are similar. For any similar figures, if the ratio of linear measurements between the two is a:b, then the ratio of area measurements between the two is a^2:b^2,and the ratio of volume measurements between the two is a^3:b^3. \n" ); document.write( "In this problem, since the ratio of the radii of the two spheres is 3:4, the ratio of their surface areas is 3^2:4^2 = 9:16. \n" ); document.write( " |
