Given a cone with a height or radius of 18yd, find the surface area and volume of the cone. Use the following formulas: 1. Surface Area (A) of a cone:
$ A = \pi r (r + \sqrt{h^2 + r^2})
\]
where \(r\) is the radius of the base and \(h\) is the height. 2. Volume (V) of a cone:
$ V = \frac{1}{3} \pi r^2 h
\] Determine whether the given measurement of 18yd is the radius or the height, and use it to calculate the surface area and volume. If only one measurement is given, assume it is the radius and provide the formulas for both scenarios.
