Answer:
Either of the following square values:
Step-by-step explanation:
The three possible answers correspond to the square of the sides of the triangles via the Pythagorean theorem. And these are:
The volume of a cone is 1/3 times the area of the base times the height.
So the area of the base would be pi times the radius squared, or 3.14 * 3.2^2, which is 32.1536.
Next you multiply 32.1536 by the height(5.8) to get 186.49088.
Then you divide that by 3 to get 62.1636267, rounded to the nearest tenth of an inch is 62.2 inches cubed.
