This ratio can be written as 8x+5x =390
Add the variables
13x = 390
Divide by 13 to get the value of x
390/13 = 30

Well, let's do the math. The formula of a cylinder is 2 (pi, which will be estimated to 3.14) r h + 2 pi (radius times radius).
First of all, do 2 x pi, which is 6.28. Multiply 6.28 x 1.4 is 8.792. 8.792 x 5 = 43.96.
Now for 2 times 3.14 again, which is 6.28. But this time, we do 1.4 x 1.4, which is 1.96. With our new number, we do 6.28 x 1.96, which is 12.3088.
Add 43.96 + 12.3088, and you get 56.2988. You can round it to 56.3. So, the answer is 56.3 inches.
The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
