Plz help -x+4= -9 this is my math hw

The cone's volume is calculated to be 12π inch³.

Step-by-step explanation:

Step 1:

First, we need to solve for the cone's height, x. According to Pythagoras' theorem, So the cone's height is 4 inches.

Step 2:

The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as itself. The radius is 3 inches and the height is 4 inches.

The cone's volume = =

So the cone's volume is 12π inch³.
