Two right circular cylinders of equal volumes have their heights in the ratio 1:2. Find the ratio of their radii.	Choose the correct choice from the following answers
A) √3:1  B) √7:1  C) √2:1  D) 2:1  E) 3:1
Explanation:   Let their heights be h and 2h and radii be r and R respectively then.   πr2h=πR2(2h)   =&gt;r2/R2 = 2h/h   =2/1   =&gt;r/R = √2/1   =&gt;r:R = √2:1   ANSWER IS √2:1
