**Steve**, Tuesday, March 27, 2012 at 1:16pmHow is this a challenge?

a google search shows up the simple formula

E=2G(r+1)

2*10^11 = 2*8*10^10(r+1)

1/8 * 10 = r+1

1.25 = r+1

0.25 = r

**Steve**, Tuesday, March 27, 2012 at 1:20pmAlso, for Bulk modulus K,

E = 3K(1-2r)

2*10^11 = 3K(1-2*.25)

2*10^11 = 1.5K

K = 1.33*10^11
