The volume of any cylinder is
Volume = (pi) x (radius of a round end)² x (height)
= (pi) x (6.1-ft)² x (1.8-ft)
= (pi) x (37.21 square feet) x (1.8-ft)
= 66.978 π cubic feet
Since π (pi) can't be written exactly, no number it appears in
can be written exactly either. The only way to indicate the
exact value of such a number is to leave the symbol 'π' in it.
