Can someone help me with this math question and can you explain it to? If so that would be great :)

Answer:
251.33, the reason is because the formula for the volume of a cylinder is height x π x (diameter / 2)2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2.

hope that makes sense
