Ответ:
Next, I explain the full resolution.
Step-by-step explanation:
First of all, we analyze the volume formula of a pyramid:
1/3 * B * h
Where h is the height of the pyramid, and B is the Area of the base of the pyramid, in this case, a square.
Then, in a circular cone, the base is a circle, so we can replace B with the area formula of a circle:
B= π * r^2
Where r is the radius of the cone
So if we replace in the original formula we have:
1/3 * π * r^2 * h
And if ππ is the radius of the cone, then the formula is:
1/3 * π * ππ^2 * h
Hope it helps!
