<em>Step-by-step explanation</em>
The volume of a cylinder is calculated as follows:

where <em>r </em>is the radius and <em>h </em>is the height of the cylinder.
In the case of cylinder A, its radius is r = 5 ft (= 10/2) and its height is h = 14 ft. Then, its volume is:

In the case of cylinder B, its radius is r = 8 ft (= 16/2) and its height is h = 8 ft. Then, its volume is:

After the pumping is completed all the liquid in cylinder A, which was full, is placed in cylinder B. If the volume of cylinder B represents 100%, then we need to find what percent, <em>x</em>, represents the volume of cylinder A. We can do this with the help of the next proportion:

Solving for x:
We can split the given figure in 2 right triangles:
So, in order to get the area of each triangle, we need to find the base, denoted by x in both of them. Since both are right triangles, we can to apply Pythagoresn theorem. By applying this theorem to right hand side triangle, we have

so we have

Then, x is given by

Then, the area of the left triangle is given by

Similarly, the area of the second triangle is given by

Then, the area of the entire figure is the sum of the area of the 2 triangles, that is,

Therefore, the answer is: 330 square inches

Step-by-step explanation:
I think thats the answer
By the binomial theorem,

where

Then the coefficients of the

(7.8×10⁷)+(9.9×10⁷)
(7.8×10000000)+(9.9×10000000)
(78000000)+(99000000)
