<h2>Answer:</h2>
The equation for r is given by:
It is given that:
The lateral surface area of a cylinder is given by the formula S=2πrh.
where π is an irrational number. r denotes the radius of the base of the cylinder and h denote the height of the cylinder.
Now, we are asked to solve for r.
i.e. we need to express r in terms of other variables with the help of the given formula.
Hence, we get:

Answer:
y = -0.2x - 5.8
Step-by-step explanation:
If a line is given in the form y = mx + b, the "m" is the slope.
For the line given y = 5x, the slope is 5
The line that is perpendicular to this will have slope that is "negative reciprocal of that".
So, the perpendicular line will have slope of
So, the Perpendicular Line will have equation:
y = -1/5x + b
Let's find b by replacing x with 6 and y with -7 [the point given]. So we have:
So the equation of perpendicular line = y = -0.2x - 5.8
