use pi x radius^2
so square the radius and times it by pi to give you the area of the circle
and then times it by 2.5 to get the area of the total prism

Volume of a cylinder = b x h = Pi x r 2 x h.
So Pi x 3.8 squared = 45.3645979 or 45.4 to 3sf, then multiplied by the height of 2.5 cm = 113.4114947 or 113.4
So the volume of your prism = 133.4 cm cubed

Volume = 3.14 x r^2 x height
Volume = 3.14 x 3.8 x 3.8 x 2.5
The answer will be ___ cubic centimeters.
