Answer:
x + y = 41
x - y = 13
------------------
2x = 54..............We divide 2 such that
x = 27
Then we plug 27 into the equation such that
27 + y = 54.................Subtract 27 to get
y = 14

The Area of a piece of paper
Answer:
602.88cm²
Step-by-step explanation:
Find the image of the cylinder attached
Surface area of a cylinder = A=2πrh+2πr²
r is the radius = 4cm
Height h = 20cm
Substitute
A = 2πr(r+h)
A = 2π(4)(4+20)
A = 8π(24)
A = 192π
A = 192(3.14)
A = 602.88cm²
Hence the surface area of the cylinder is 602.88cm²
