pi times 0.1055 ie 0.33 units, to two significant figures
First you do the area for the base which is a=3.14r2. So 9 units is the diameter. 4.5 is the radius. The answer for the base is 63.6. So volume equals base x height. You do 63.6 x 2.5 and the answer is 159.
The volume of a cylinder 2.1 meters in diameter and 2.3 meters high is 7.97 cubic meters.
