1) the area of the "side" of the cylinder is A1= pi (4 in).
2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in)^2 (since the radius of the cyl. is 2 in).
The desired total surface area is A = A1 + A2. Keep "pi;" do not substitute a numerical value for "pi."
Answer:
27x - 2
Step-by-step explanation:
First off, we use commutative property to get the like terms together.
(20x + 7x) - (3-5)
Now we can solve the equations inside the parenthesis.
27x - (-2)
Because these aren't like terms, this is as far as we can go. Meaning 27x - 2
is out answer.
