Question 1136640

Since the end (base) of a cylinder is a circle, the area of that circle is given by the formula:
area	{{{A=pi* r^2}}}  

Multiplying by the height {{{h}}} we get volume:

{{{V=pi* r^2*h}}}

given: 

a base diameter {{{d=18in}}}=> radius is {{{r=9in}}}  

and a height of {{{h=2in}}}


then we have


{{{V=3.14* (9in)^2*2in}}}


{{{V=3.14* 81in^2*2in}}}


{{{V=508.7in^3}}}
