Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
Answer: A

2y = 8
divide by 2
y = 4
13/6-9/7
Find the Least Common Denominator (LCD)
In this case, 42.
(7/7)(13/6)-(6/6)(9/7)
37/42 is your answer
