205-2d
That's the expression. 205 you start with, every day, you add two, so 2*d is logical.
Let
x---------> radius of the cylinder
y---------> the height of the cylinder
we know that
x=2y
[surface area of cylinder]=2*[pi*r²]+2*pi*r*h
surface area=108*pi m²
r=x
h=y
x=2y
108*pi=2*[pi*(2y)²]+2*pi*(2y)*y
108*pi=8*pi*y²+4*pi*y²
108*pi=12*pi*y²
y²=108/12
y²=9----------> y=√9--------> y=3 m
x=2y-------> x=2*3-----> x=6 m
the answer is
the height of the cylinder is 3 m

Find c
The question is incomplete. However, I'll assume the expression is a perfect square.
To find c, we make use of the following formula

Where

By comparison with 


So,
becomes
