length =88cm
breadth=21cm
when it is rolled it becomes cylinder
having circumference 88cm
2πr=88cm
r=88×7/44
r=14
h=21
total surface area of the cylinder =2πr(r+h).
=2×22/7×14(14+21)
=3080cm²
The answer is going to be H because if you plug in x from the table it will give you y.
1/2=6, 6÷1/2=12, 1=12 because if 1/2×12=6, then 1×12=12
Radius = 100m
Circumference of a circle = 2πr
= 2 × π× 100
=628.31m
