Answer:

8pi(3x+1)^2 inches^2

Step-by-step explanation:

A=2πrh+2πr^2

A=2pi(3x+1)3(3x+1)+2pi (3x+1)^2

A=6pi(3x+1)^2+2pi(3x+1)^2

A=8pi(3x+1)^2

In case you're confused, first, write out the surface area of a cylinder out, it's a specific formula. Then, plug in your radius and height. It says that the height is 3 times the radius, so that's 3(3x+1).

I hope this helped! If you have any questions or concerns, please don't hesitate to comment them down below! Have a good rest of your day!

<h3>Step-by-step explanation:</h3>

Here from the given graph we can see that the graph the graph intersects x axis at (2,0) and y axis at (5,0). On seeing options it's clear that we have to use Slope intercept form . Which is :-

$\large\boxed{\orange{\bf y = mx + c} }$
