When x=9 the expression is undefined.

That is because any number over 0 is undefined, including 0/0.

The figure is made up of a cone and a cylinder.

Diameter = 16 ft
radius = 16÷2 = 8ft

Volume of the cone = 1/3bh
Volume of the cone = $\frac{1}{3} \pi r^{2} h$
Volume of the cone = $\frac{1}{3} \pi 8^{2}(6)$ = 402.12

Volume of the cyclinder = bh
Volume of the cylinder = $\ \pi r^{2} h$
Volume of the cylinder = $\ \pi 8^{2}(4)$ = 1206.37

Total = 402.12 + 1206.37 = 1608.49 cubic feet
