To find the volume of a cone, you can use the formula:
V = (1/3)Ï€r^2h
where r is the radius of the base of the cone and h is the height of the cone.
In this case, the radius (r) is 9 yd and the height (h) is 17 yd.
V = (1/3)Ï€(9^2)(17)
V = (1/3)Ï€(81)(17)
V = (1/3)Ï€(1377)
V ≈ 1445.4 cubic yards
So, the volume of the cone would be approximately 1445.4 cubic yards when rounded to the nearest tenth.
