The surface area of a cylinder is 2*pi*r*h(side area)+2*pi*r^2(bases).
When you plug in the values: 2*pi*5*8+2*pi*25 = 80pi+50pi
Answer: 130pi
My answer is C because without medics for instance if you had the flu and no medicine you would die
Solving for a gives us: 
Step-by-step explanation:
Solving an equation for a variable means that we have to isolate the variable in the equation
Given equation is:

For isolating a, subtracting c from both sides

Subtracting b from both sides

Hence,
Solving for a gives us:

Answer:
72 units
Step-by-step explanation:
There are two ways to solve the problems.
Count graphically, horizontally there are 9 units, vertically there are 8 units in the rectangle. So the area is 9*8 = 72 units.
Alternatively, check the difference between two adjacent vertices,
1. between (4,-3) and (4,5), the difference is (0,8), or 8 units.
2. between (4,5) and (-5,5), the difference is (9,0), or 9 units.
So again, the area of the square is 8*9=72 units.
The value a is 7.
<h3>What is Straight Line?</h3>
A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.
Here, the given equation of line
y = ax -3
line passing through point (2, 11), then
11 = a X 2 - 3
11 + 3 = 2a
2a = 14
a = 7
Thus, the value a is 7.
