A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:
Which of the following could be used to calculate the total volume of grains that can be stored in the silo?
π(8.5ft)2(2ft) + one over threeπ(2ft)2(13ft − 8.5ft)
π(2ft)2(8.5ft) + one over threeπ(2ft)2(13ft − 8.5ft)
π(8.5ft)2(2ft) + one over threeπ(13ft − 8.5ft)2(2ft)
π(2ft)2(8.5ft) + one over threeπ(13ft − 8.5ft)2(2ft)

Best ResponseYou've already chosen the best response.0Ok the volume of the cylindrical part = π r^2 h where r = radius (which is half the diameter) and h = height

Best ResponseYou've already chosen the best response.0and the volume of the cone = (1/3) π r^2 h where r=radius and h = height

Best ResponseYou've already chosen the best response.0now check out the diagram to find these values and plug them into the above formulas

Best ResponseYou've already chosen the best response.0ok but try and work the formula out radius = 1/2 * 4 = 2 and height of the cylinder = 8.5 what is the height of the cone?

Best ResponseYou've already chosen the best response.0and volume of the cone = 1/3 π 2^2 * h and h = difference (13  8.5) so which of the choices is correct?

Best ResponseYou've already chosen the best response.0the volumes of the cyl and cone are of course added together

Best ResponseYou've already chosen the best response.0have a close look at a and b. It is one of those Which one?

Best ResponseYou've already chosen the best response.0putting the volumes together we have π* 2^2 * 8.8 + 1/3 π 2^2 * (13  8.5)

Best ResponseYou've already chosen the best response.0oh a typo  that should be 8.5 not 8.8

Best ResponseYou've already chosen the best response.0a is π* 8.5^2 * 2 + 1/3 π 2^2 * (13  8.5)
