Answer:
a) 6312.12 lbm
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
[tex] = 196.211\times 32.17 = 6312.12 lbm[/tex]
b) waist to height ratio = 0.5
[tex]waist\ to\ height\ ratio = \frac{circumference\ of\ the\ waist}{height\ of\ the\ person}[/tex]
circumference of waist =[tex] height\ of\ person \times waist\ to\ height ratio[/tex]
[tex]= 74.41 inch \times 0.5[/tex]
=37.21 inch
we know that circumference is given as [tex]= 2\pi r\ or\ \pi D= 37.21[/tex]
D = 11.843 inch
