## anonymous one year ago What is the heating capacity, in BTUs, of a cylindrical storage tank of propane with a radius of 3 feet and a height of 10 feet? Assume that 1 cubic foot of propane contains 2,516 BTUs and 1 cubic foot of natural gas contains 1,030 BTUs. Use 3.14 for pi, and round your answer to the nearest BTU.

Start by finding the volume of the tank V = πr²h

yes, but they want you to round π to 3.14 so it comes out to 282.6 ft³ when you do that

ok

Now you can use the conversion factor for propane $282.6 ft^3 \times \frac{ 2516~ BTU }{ 1~ft^3 }$

so I just plug that into my calculator?

yes
