Find the surface area of the cylinder. Round your answer to the nearest tenth.

ANSWERS: 282,9CM

Step-by-step explanation: 2 PIE R (R + H)

R=6 /2=R=3

=2 X 22/7 X 3(3 + 12)

=132/7 (15)

=1980/7

=282.857

=282.9CM

If we take the adjacent side AD and DC  and work out their slopes we get 

AD = (6-4)/(2-0)  = 1 and DC has slope (6-4)/(2-4)  = -1 . This shows that the angle between the 2 lines is 90 degrees so it looks like  this is a square.
