WebbQuestion If the radius of a sphere is doubled, then what is the ratio of their volumes? Easy Solution Verified by Toppr Let the original radius be r so the original volume = 34πr 3 New radius = 2r so, new volume = 34π(2r) 3= 34π(8r 3) Ratio = 34π(8r 3) 34πr 3 = 81 so ratio = 1:8 Was this answer helpful? 0 0 Similar questions WebbThe radius of a sphere is 2r, then its volume will be Answer: (D) (32πr3)/3 Explanation: Given, the radius of a sphere is 2r.
