Answer:

A: 50/80

Step-by-step explanation:

A ratio will form a proportion with 5/8 when it is equal to 5/8. (A proportion is a statement that two ratios are equal.)

The offered fractions have reduced values of ...

50/80 = 5/8 . . . . . the ratio you're looking for
40/80 = 1/2
55/64 = 55/64
50/88 = 25/44

As you can see, only the first answer choice has a value of 5/8, so that is the one that will form a proportion with 5/8:

5/8 = 50/80

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
