Answer: 128.26 cubic cm.
Step-by-step explanation: The first thing you need to do is find the volume of the jar. First find the radius of the base by dividing the diameter by 2. 6/2=3. Square the radius. 3^2=9. Multiply by pi (3.14). 9*3.14=28.26. Multiply this by the height. 28.26*8=226.08.
Next find 70% of 226.08. Convert 70% to a decimal by dividing by 100. 70/100=0.7. Multiply this by 226.08. 226.08*0.7= 128.256. Round this to the nearest hundredth if you want to by rounding up the 5 to get 128.26.
