Answer:

Height, h = 20.99 millimeters.

Explanation:

Given the following data;

Volume = 8792mm³

Radius = 20 mm

To find the height;

We know that the shape of an anthill is conical in nature.

Mathematically, the volume of a cone is given by the formula;


V = (1)/(3) \pi r^(2)h

Where;

  • V is the volume of the cone.
  • r is the radius of the base of the cone.
  • h is the height of the cone.

Substituting into the equation, we have;


8792 = (1)/(3) * 3.142*20^(2)*h


8792 = (1)/(3) * 3.142*400*h


8792 = (1)/(3) * 1256.8*h


8792 = 418.93*h


Height, h = \frac {8792}{418.93}

Height, h = 20.99mm.

Therefore, the height of the cone is 20.99 millimeters.
