What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?

ft3


Sagot :

AL2006

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.
