When two variables are directly or indirectly proportional to each other, then their relationship can be described as y = kx or y = k/x, where k determines how the two variables are related to one another.

Step-by-step explanation:

This k is known as the constant of proportionality.

A right circular cylinder has a height of 19 3/4 ft and a diameter 1 2/5 times its height.

Y_Kistochka [10]

Height of cylinder = $19\frac{3}{4} =19.75$ ft

Diameter of cylinder = $1\frac{2}{5}$ times its height = $1.4 * 19.75=27.65$ ft

Now Radius = half of diameter = $\frac{27.65}{2} =13.825$ ft

Now we have to find the Volume of cylinder

formula for Volume of cylinder is

Volume of cylinder = $\pi r^2 h$

let's plug the values

Volume of cylinder = $(3.14)*(13.825)^2 *(19.75)$

Plug the values in calculator

= 11852.9657 cubic feet

Round off the answer to two decimal places(i.e. hundredth)

= 11852.97 cubic feet
