d=1,16 m  
h=0,16 m  
glass density 2500 kg/m3

1  
Measure diameter  
use formula A=πd2/4 => 3.14\*1.16\*1.16/4=1.056296 m2  
Multiply by cylinder height => 1.056296\*0.16=0.169 m3  
Multiply by glass density => 0.169\*2500=422.5184 kg  
2  
Measure diameter  
Calculate radius from diameter r=d\\2=0.58 m  
use formula A=πr2 => 3.14\*0.58\*0.58=1.056296 m2  
Multiply by cylinder height => 1.056296\*0.16=0.169 m3  
Multiply by glass density => 0.169\*2500=422.5184 kg
