Question 116963
The volume of a cylinder is {{{Pi*(r^2) h}}} where {{{r}}} is the radius and{{{ h}}} is the height.

You are given:
	{{{h =35 ft}}} 
{{{d =12 ft}}} ….. {{{diameter = 2r}}}…=>….{{{r=d/2=12ft/2=6ft}}}

The volume {{{V}}} of a cylinder is {{{Pi* (r^2) h}}}

Find a {{{V}}}:

	{{{V = Pi* (r^2 )h }}}

	{{{V = Pi* (r^2) h }}}

	{{{V = 3.14(6ft)^2 (35 ft) }}}

	{{{V = 3.14*36ft^2 *35 ft}}}

	{{{V = 113.04ft^2 *35 ft}}}

	{{{V = 3956.4ft^3}}}

Since one cubic foot is {{{7.48}}} gallons, we will have:	

{{{3956.4/7.48=528.93 }}}...gallons
