The height of the cone is approximately 11 mm.

Solution

  1. The formula for the volume of a cone is:
    \[V = \frac { 1} { 3} \pi r^ 2 h\]
  2. Given:
    • Diameter = 14 mm, so the radius \(r = \frac { 14} { 2} = 7\) mm.
    • Volume \(V = 564.15\) mm\(^ 3\).
  3. Substitute the known values into the volume formula:
    \[564.15 = \frac { 1} { 3} \pi ( 7) ^ 2 h\]
  4. Simplify the equation:
    \[564.15 = \frac { 1} { 3} \pi ( 49) h\]
    \[564.15 = \frac { 49} { 3} \pi h\]
    \[564.15 = 16.3333 \pi h\]
  5. Solve for \(h\):
    \[h = \frac { 564.15} { 16.3333 \pi } \]
    \[h = \frac { 564.15} { 16.3333 \times 3.14} \]
    \[h = \frac { 564.15} { 51.3146} \]
    \[h \approx 10.99\]
  6. Round to the nearest whole number:
    \[h \approx 11\]
    Therefore, the height of the cone is approximately 11 mm.

 

Supplemental Knowledge

The volume \(V\) of a cone is given by the formula:
\[V = \frac { 1} { 3} \pi r^ 2 h\]
where \(r\) is the radius of the base, \(h\) is the height, and \(\pi \) (pi) is approximately 3.14.
