b) D = 11.843 inch
Explanation:
GIVEN DATA:
Height of person = 1.89 m = 74.41 inch
mass of person m = 89 kg = 196.211 lbm
a) person earth weight =mg
where g is acceleration due to gravity = 32.17 ft/sec^2
b) waist to height ratio = 0.5
circumference of waist =
=37.21 inch
we know that circumference is given as 
D = 11.843 inch
