In this question , it is given that we have a cylinder with with a radius of 9 and a surface area of approximately 791.68 units square.

The formula of surface area of cylinder is

A= 2 \pi r^2 + 2 \pi r h

Substituting the values of A and r, we will get

791.68 = 2* \pi * 9^2  + 2 * \pi * 9*h
\\
791.68 = 162 \pi + 18 \pi h
\\
791.68 -162 \pi = 18 \pi h
\\
h = \frac{791.68 -162 \pi}{18 \pi}
\\
h =5 units

So the height of the cylinder is 5 units .

5p - 14 = 8 p + 4 No solution, Infinitely many solutions, 6 ,-6​
DedPeter [7]

Answer:

-6

Step-by-step explanation:

5p - 14 = 8p + 4

Subtract 8p from both sides.

-3p - 14 = 4

Add 14 to both sides.

-3p = 18

Divide both sides by -3.

p = -6

Answer: -6
