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)

does (2ft)2 mean 2 feet squared?

Ok the volume of the cylindrical part = π r^2 h where r = radius (which is half the diameter) and h = height
welshfella
  • welshfella
and the volume of the cone = (1/3) π r^2 h where r=radius and h = height
welshfella
  • welshfella
now check out the diagram to find these values and plug them into the above formulas

  • anonymous
okay im thinking a or b
welshfella
  • welshfella
ok 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?
welshfella
  • welshfella
cylinder = π r^2 h = π * 2^2 * what ?

im finding the volume of the cylinder?
welshfella
  • welshfella
yes what comes after the 2^2?
welshfella
  • welshfella
h right what is h?
anonymous
  • anonymous
the volume would be 106.81
anonymous
  • anonymous
h is height
welshfella
  • welshfella
yes and h = ?
anonymous

8.5**
welshfella
  • welshfella
right vol of cyl = π* 2^2 * 8
anonymous
  • anonymous
right
welshfella
  • welshfella
and volume of the cone = 1/3 π 2^2 * h and h = difference (13 - 8.5) so which of the choices is correct?
welshfella
  • welshfella
the volumes of the cyl and cone are of course added together
welshfella
  • welshfella
have a close look at a and b. It is one of those Which one?
welshfella
  • welshfella
putting the volumes together we have π* 2^2 * 8.8 + 1/3 π 2^2 * (13 - 8.5)
welshfella
  • welshfella
a or b?
welshfella
  • welshfella
oh a typo - that should be 8.5 not 8.8
anonymous
  • anonymous
a?
welshfella
  • welshfella
a is π* 8.5^2 * 2 + 1/3 π 2^2 * (13 - 8.5)
welshfella
  • welshfella
check this against what we worked out
welshfella
  • welshfella
is 8.5 the radius and 2 the height??
welshfella
  • welshfella
i gotta go right now - check out my posts i'm sure you can work it out
