A sphere and a cube has same surface area find the ratio of their volumes
Read Solution (Total 1)
-
- given equal surface area
=> 4*pi*r^2 = 6 *a^2
=> (r/a)^2 = 6/(4*pi)
now ratio of volume,
(4/3*pi*r^3)/(a^3)
= (4*pi*(r^2)*r)/(3*(a^2)*a)
= (6^1/2)/(pi^1/2)
ratio is, 6^0.5 : pi ^0.5 - 10 years agoHelpfull: Yes(1) No(0)
