The area of a circle is equal to

therefore
the answer is

Answer:
x^2 + 2xy + y ^2
Step-by-step explanation:

a = x + y
(x + y) + (x + y)
x^2 + xy + xy + y^2
x^2 + 2xy + y ^2
Answer:
-2
Step-by-step explanation:
7x-21-10x+20=5
7x-10x-1=5
-3x=5+1

x=-2
Answer:
or 
Step-by-step explanation:
The lateral area of a cylinder is calculated by the following formula

Where r is the radius of the right cylinder and h is the height
In this case we know that the diameter d of the cylinder is


Therefore the lateral area is:
