Answer:
25.12cm
Step-by-step explanation:
So we first find the area of the circle on top:
area= 
or 3.14 x 
which equals 12.56
Then we multiply it by 2:
12.57 x 2 = 25.12
So the lateral surface area is 25.12cm
9514 1404 393
Answer:
divide by x
Step-by-step explanation:
To answer your question, you can get from A to B by dividing by x:

However, this is only a valid operation if x ≠ 0. In this equation, x = 0, so that division is not valid.

A better approach to the solution is to put the equation in standard form:
f(x) = 0
You can get there by subtracting 3x from both sides.
5x -3x = 3x -3x
2x = 0
Now, you can legitimately divide by 2 to find ...
x = 0 . . . . . . . . the reason why dividing by x is not allowed
