Volume of a cylinder = area of the base circle x height of the cylinder
area of the circle = 22/7*r^2
Volume of a cylinder =22/7*r^2*h=792sq.cm
here r=6/2 & h=28 & radius sq.=9
value of pi is 3.147 to be more precise its 22/7

volume of cylinder= (22/7)*radius*height
= (22*3*28)/7 cm
= 264cm

Hey, look - another kid who doesn't want to do his own homework!!!
Find the area of the circle on the end of the cylinder - look in the index of your text for this formula. Then multiply that by the height of the cylinder.
For extra credit, convert your measurements to cubic inches.

formula=22/7*r^2*h=792sq.cm
here r=6/2 & h=28 & radius sq.=9
and 22/7=3.14 & is called pie
