Question

The diagram shows the dimensions of a teepee. Find the volume of the building to the nearest cubic unit. Use 3.14 for pi.

Answer 1

The volume of a cone uses the following formula:


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

Our diameter is 20 feet, so divide this by 2 to find the radius:


`20 / 2 = 10`

We now have all of our values need to fill in the formula. Plug in these values:


`\pi = 3.14, r = 10, h = 17`


`3.14 * 10^(2) * (17)/(3)`


`3.14 * 100 * 5.67`


`314 * 5.67 = 1780.38`

The volume of the cone is 1780 cubic feet.
