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

Substituting the values of A and r, we will get

So the height of the cylinder is 5 units .
G=3
If you multiply out x+7 and x-4 you get <span>x^2+3x-28
The 3 in the above equation is like the G</span>
12-9=3
3+12+4,5=19,5
