I'm not sure if I did this problem right, but I think the answer is 0.067? Could someone please check my answer?

**Steve**, Thursday, February 9, 2012 at 8:22pmV/v = (R/r)^3

A/a = (R/r)^2

so,

V/v = (A/a)^3/2

= (53.78/8.92)^3/2

= 6.029^3/2 = 14.80

Oops. You wanted v/V = 0.0675

You are correct
