Remember the formula of volume, if diameter is 1.6, then the radius is the half =0.8 and now use the formula

anonymous · Answer

i would do 3.14 x 225 x1.6 right?

rephrasing the question what is the volume of a cylinder with height 15 meters and diameter 1.6 meters   use 3.14 for pi

anonymous · Answer

no, 1.6 is the diameter, you have to use the radius

anonymous · Answer

radius is half of diameter
