Answer: 
Step-by-step explanation:
From the given picture, the radius of the base of the cylinder = 5.5 ft.
The height of the cylinder = 5 ft.+6 ft.=11 ft.
We know that the surface area of a cylinder is given by :-

Hence, the surface area of the given cylinder =

Answer:
-14n^4 + 7n^2 + 8n + 7
Step-by-step explanation:
( 8n - 3n^4 + 10n^2 ) - ( 3n^2 + 11n^4 - 7)
8n - 3n^4 + 10n^2 - 3n^2 - 11n^4 + 7
- 14n^4 + 7n^2 + 8n + 7
<span>Rational
expressions are defined as the quotients of two integers in which the
denominator does not equal to zero. Thus, the numerator and denominator would
be polynomials, which is a form of a system analogous to the integers under the
operation of addition, subtraction and multiplications. Therefore, the key
numbers of rational expressions are its variables in the numerator and/ or
denominator.</span>
