A metal sphere is found floating in a pool. The sphere is 1m in diameter. If it is half submerged determine the weight of the sphere. You may assume the following:

g=10N/kg
density of Water = 1000kg/m^3
Vsphere = 4/3pir^3

I get 13.3 as my final answer, but there is no answer in this book to tell me if I am correct or not >>

R=0.5 m
W= mg
mg =F(buoyant)

W = (1/2) •(4πR³/3) •ρ•g =
=1000•4π•0.5³•10/2•3=
=2618 N
