So we wan't to find the volume of a cone shaped crater that has a diameter d=72 yd and a height h=24 yd. The formula to get the volume of a cone is V=(1/3)*pi*(r^2)*h. So first we need to find the radius from the diameter. The diameter is 2 radii or: d=2r so r=36 yd. Now we can input our numbers into the formula for volume and we will get V=32555.52 yd^3.
