Question 210034
Equation for the Volume of a Cone:
{{{v=(1/3)pi(r^2)h}}}
You are given r and h, so plug and chug...
{{{v=(1/3)pi(3^2)10}}}
{{{v=(1/3)pi(90)}}}
{{{v=30pi}}}
{{{v=94.2}}} cubic feet
To determine how many gallons this is, just use the conversion information given in the problem. I will leave that part up to you.
